Introduction
This document will describe the API of libEtPan!
Tools and datatypes
libEtPan! include a collection of datatypes such as lists,
arrays, hash tables and tools such as buffered I/O.
Array
#include <libetpan/libetpan.h>
typedef struct carray_s carray;
carray is an array of pointers that will
resize automatically in case a new element is added.
The carray is implemented with an array
(void **) that can be resized. An array has a
size: this is the number of elements that can be added before
the table is resized. It also has a count of elements: this is
the elements that exist in the array.
carray_new and carray_free
carray * carray_new(unsigned int initsize);
void carray_free(carray * array);
carray_new() creates a new array with an
initial size. The array is not resized until the number of
element reach the initial size. It returns
NULL in case of failure.
carray_free() releases memory used by the
given array.
carray creation
#include <libetpan/libetpan.h>
#include <stdlib.h>
#define SIZE 50
int main(void)
{
carray * a;
a = carray_new(SIZE);
if (a == NULL)
exit(EXIT_FAILURE);
/* do things here */
carray_free(a);
exit(EXIT_SUCESS);
}
carray_set_size
int carray_set_size(carray * array, uint32_t new_size);
carray_set_size() sets the size of the
array. It returns 0 in case of success,
-1 in case of failure.
preallocating carray
#include <libetpan/libetpan.h>
#include <stdlib.h>
#define SIZE 50
#define NEWSIZE 200
int main(void)
{
carray * a;
unsigned int i;
char p[500];
a = carray_new(SIZE);
if (a == NULL)
goto err;
r = carray_set_size(NEWSIZE);
if (r < 0)
goto free;
for(i = 0 ; i < NEWSIZE ; i ++)
carray_set(a, i, &p[i]);
/* do things here */
carray_free(a);
exit(EXIT_SUCESS);
free:
carray_free(a);
err:
exit(EXIT_FAILURE);
}
carray_count, carray_add, carray_get and carray_set
int carray_count(carray);
int carray_add(carray * array, void * data, unsigned int * index);
void * carray_get(carray * array, unsigned int indx);
void carray_set(carray * array, unsigned int indx, void * value);
carray_count() returns the number of
elements in the carray.
Complexity is O(1).
carray_add()adds an element at the end of
the array. The index of the element is
returns in (* index) if
index is not NULL. It
returns 0 in case of success,
-1 in case of failure.
Complexity is O(1).
carray_get() returns the elements contained
at the given cell of the table.
Complexity is O(1).
carray_set() replace the element at the
given index of table table with the given value.
Complexity is O(1).
carray access

#include <string.h>
#define SIZE 50
int main(void)
{
carray * a;
int r;
a = carray_new(SIZE);
if (a == NULL)
goto err;
r = carray_add(a, "foo-bar-1", NULL);
if (r < 0)
goto free;
carray_add(a, "foo-bar-2", NULL);
if (r < 0)
goto free;
carray_add(a, "foo-bar-3", NULL);
if (r < 0)
goto free;
for(i = 0 ; i < carray_count(a) ; i ++) {
char * str;
str = carray_get(a, i);
if (strcmp("foo-bar-2", str) == 0)
carray_set(a, i, "foo-bar-2-replacement");
printf("%s\n", str);

int carray_delete_slow(carray * array, uint32_t indx);
int carray_delete_fast(carray * array, uint32_t indx);
carray_delete() removes an element of the
table. Order will not be garanteed. The returned result can
be ignored.
Complexity is O(1).
carray_delete_slow() removes an element of
the table. Order will be garanteed. The returned result can
be ignored.
Complexity is O(n).
carray_delete_fast() the element will just
be replaced with NULL. Order will be kept
but the number of elements will remains the same. The
returned result can be ignored.
Complexity is O(1).

typedef struct chashcell chashiter;
typedef struct {
char * data;
int len;
} chashdatum;
chash is a hash table.
chashiter is a pointer to an element of the
hash table.
chashdatum is an element to be placed in
the hash table as a key or a value. It consists in
data and a corresponding length.
chash_new and chash_free
#define CHASH_COPYNONE 0
#define CHASH_COPYKEY 1
#define CHASH_COPYVALUE 2
#define CHASH_COPYALL (CHASH_COPYKEY | CHASH_COPYVALUE)
chash * chash_new(int size, int flags);
void chash_free(chash * hash);
chash_new() returns a new empty hash table
or NULL if this
failed. size is the initial size of the
table used for implementation. flags can
be a combinaison of CHASH_COPYKEY and
CHASH_COPYVALUE.
CHASH_COPYKEY enables copy of key, so
that the initial value used for chash_set()
chash_free() releases memory used by the
hash table.
chash_set and chash_get
int chash_set(chash * hash,
chashdatum * key, chashdatum * value, chashdatum * oldvalue);
int chash_get(chash * hash,

hash table. If a previous element had the same key, it is
returns into oldvalue if oldvalue is
different of NULL.
Medium complexity is O(1).
returns -1 if it fails, 0 on success.
chash_get()returns the corresponding value
of the given key. If there is no corresponding value, -1 is
returned. 0 on success.

int mailstream_close(mailstream * s);
mailstream_new() creates a new stream
stream with the low-level (see )
stream and a given buffer size.
mailstream_close() closes the stream.
This function will be in charge to free the
mailstream_low structure.

ssize_t mailstream_read(mailstream * s, void * buf, size_t count);
ssize_t mailstream_feed_read_buffer(mailstream * s);
mailstream_write() writes a buffer to the
given stream. This write operation will be buffered.
mailstream_flush() will force a write of
all buffered data for a given stream.
mailstream_read() reads data from the
stream to the given buffer.
mailstream_feed_read_buffer() this function
will just fill the buffer for reading.
mailstream_low * mailstream_get_low(mailstream * s);
void mailstream_set_low(mailstream * s, mailstream_low * low);
mailstream_get_low() returns the low-level
stream of the given stream.
mailstream_set_low() changes the low-level
of the given stream. Useful, for
example, when a stream change from clear stream to SSL
stream.

size_t progr_rate,
progress_function * progr_fun);
mailstream_read_line() reads an entire line
from the buffer and store it into the
given string. returns NULL on error, the
corresponding array
of char is returned otherwise.
mailstream_read_line_append() reads an entire
line from the buffer and appends it to the
given string. returns NULL on error, the
array of char corresponding to the entire buffer is returned
otherwise.
mailstream_read_line_remove_eol() reads an
entire line from the buffer and store it into the
given string. All CR LF are removed.
returns NULL on error, the corresponding
array of char is returned otherwise.
mailstream_read_multiline() reads a
multiline data (several lines, the data are ended with
a single period '.')
from the given stream and store it into the given
multiline buffer (multiline_buffer). progr_rate should be 0
and progr_fun NULL (deprecated things).
stream_buffer is a buffer used for internal
work of the function.
size should be 0 (deprecated things).
int mailstream_is_end_multiline(char * line);
returns 1 if the line is an end of multiline data (a single
period '.', eventually with CR and/or LF). 0 is returned
otherwise.
int mailstream_send_data(mailstream * s, char * message,
size_t size,
size_t progr_rate,
progress_function * progr_fun);
sends multiline data to the given stream.
size is the size of the data.
progr_rate and progr_fun
are deprecated. progr_rate must be 0,
progr_fun must be NULL.
socket stream
mailstream * mailstream_socket_open(int fd);
mailstream_socket_open() will open a
clear-text socket.
TLS stream
mailstream * mailstream_ssl_open(int fd);

};
mailstream_low is a non-buffered stream.
The mailstream_low_driver is a set of
functions used to access the stream.
mailstream_read/write/close() is the same
interface as read/write/close()
system calls, except that the file descriptor is replaced with the
mailstream_low structure.
mailstream_get_fd() returns the file
descriptor used for this non-buffered stream.
mailstream_free() is in charge to free
the internal structure of the mailstream_low and the
mailstream_low itself.
mailstream_low * mailstream_low_new(void * data,
mailstream_low_driver * driver);
mailstream_low_new() creates a low-level mailstream with the

referencing string
int mmap_string_ref(MMAPString * string);
int mmap_string_unref(char * str);
MMAPString provides a mechanism that let you use MMAPString
like normal strings. You have first to use
mmap_string_ref(), so that you notify
that the string will be used as a normal string, then, you
use mmapstr->str to refer to the
string. When you have finished and you want to free a string
corresponding to a MMAPString, you will
use mmap_string_unref.
mmap_string_ref() references the string
so that the array of characters can be used as a normal
string then released with
mmap_string_unref().
The array of characters will be obtained with string->str.
returns -1 on error, 0 on success.
Internet Message Format
libEtPan! implements Internet Message parser. Currently, format
is RFC 2822.
This module also allows to generate messages.
All allocation functions will take as argument allocated data
and will store these data in the structure they will allocate.
Data should be persistant during all the use of the structure
and will be freed by the free function of the structure
allocation functions will return NULL on failure
functions returning integer will be returning one of the
following error code:
MAILIMF_NO_ERROR,
MAILIMF_ERROR_PARSE,
MAILIMF_ERROR_MEMORY,
MAILIMF_ERROR_INVAL,
or MAILIMF_ERROR_FILE.
Quick start
You will need this module when you want to parse headers
of messages or when you want to build message headers
conformant to standards.
Parse message headers
You will use one of the four following functions, depending
on your needs :
mailimf_envelope_and_optional_fields_parse
(),
mailimf_envelope_fields_parse
(),
mailimf_optional_fields_parse
(),
mailimf_fields_parse
().
Render the message headers
Build your message headers, then use
mailimf_fields_write
()
to render the headers.

mailimf_fields is the native structure that IMF module will use,
this module will provide an easier structure to use when
parsing fields.
mailimf_single_fields is an easier structure to get parsed fields,
rather than iteration over the list of fields
fld_orig_date is the parsed "Date"
field
(see ).
fld_from is the parsed "From" field
(see ).
fld_sender is the parsed "Sender "field
(see ).
reply_to is the parsed "Reply-To" field
(see ).
fld_to is the parsed "To" field
(see ).
fld_cc is the parsed "Cc" field
(see ).
fld_bcc is the parsed "Bcc" field
(see ).
fld_message_id is the parsed
"Message-ID" field.
(see ).
fld_in_reply_to is the parsed
"In-Reply-To" field.
(see ).
fld_references is the parsed
"References" field.
(see ).
fld_subject is the parsed "Subject" field
(see ).
fld_comments is the parsed "Comments" field
(see ).
fld_keywords is the parsed "Keywords" field
(see ).
mailimf_single_fields_new() creates and
initializes a data structure with a value.
Structures given as argument are referenced by the created

mailimf_single_fields_free() frees memory
used by the structure and
substructures will NOT be
released. They should be released by the application.
mailimf_single_fields_init() will
initialize fill the data structure, using
the given argument (fields). The
interesting fields will be filled into
single_fields.

MIME
libEtPan! implements a MIME message parser (also known as
messages with attachments or
multipart messages). This also allows to generate MIME messages.
All allocation functions will take as argument allocated data
and will store these data in the structure they will allocate.
Data should be persistant during all the use of the structure
and will be freed by the free function of the structure
allocation functions will return NULL on failure
functions returning integer will be returning one of the
following error code:
MAILIMF_NO_ERROR,
MAILIMF_ERROR_PARSE,
MAILIMF_ERROR_MEMORY,
MAILIMF_ERROR_INVAL,
or MAILIMF_ERROR_FILE.
Quick start
You will need this module when you want to parse a MIME
message.
Parse MIME message
You will use the following function :
mailmime_parse
()
Render the MIME message
Build your MIME message, then use
mailmime_write
()
to render a MIME message.
Data types
mailmime_composite_type - Composite MIME type
#include <libetpan/libetpan.h>
enum {
MAILMIME_COMPOSITE_TYPE_ERROR,
MAILMIME_COMPOSITE_TYPE_MESSAGE,
MAILMIME_COMPOSITE_TYPE_MULTIPART,
MAILMIME_COMPOSITE_TYPE_EXTENSION
};
struct mailmime_composite_type {
int ct_type;
char * ct_token;
};
struct mailmime_composite_type *
mailmime_composite_type_new(int ct_type, char * ct_token);
void mailmime_composite_type_free(struct mailmime_composite_type * ct);
This is a MIME composite type such as message or
multipart.
ct_type can have one of the 3 following values :
MAILMIME_COMPOSITE_TYPE_MESSAGE when the
composite MIME type
is message,
MAILMIME_COMPOSITE_TYPE_MULTIPART when
the composite MIME type
is multipart,
MAILMIME_COMPOSITE_TYPE_EXTENSION for
other and ct_token is set
in this case.
MAILMIME_COMPOSITE_TYPE_ERROR is used
internally on parse error.
mailmime_composite_type_new() creates and
initializes
a data structure with a value.
Structures given as argument are referenced by the created
object and will be freed if the object is released.
mailmime_composite_type_free() frees
memory used by
the structure and substructures will also be released.
create and display MIME composite type
#include <libetpan/libetpan.h>
int main(void)
{
struct mailmime_composite_type * ct;
ct = mailmime_composite_type_new(MAILMIME_COMPOSITE_TYPE_MULTIPART, NULL);
/* do your things ... */
mailmime_composite_type_free(ct);
exit(EXIT_SUCCESS);
}
void display_composite_type()
{
switch (ct->type) {
case MAILMIME_COMPOSITE_TYPE_MESSAGE:
printf("composite type is message\n");
break;
case MAILMIME_COMPOSITE_TYPE_MULTIPART:
printf("composite type is multipart\n");
break;
case MAILMIME_COMPOSITE_TYPE_EXTENSION:
printf("composite type: %s\n", ct->ct_token);
break;
}
}
mailmime_content - MIME content type (Content-Type)
#include <libetpan/libetpan.h>
struct mailmime_content {
struct mailmime_type * ct_type;
char * ct_subtype;
clist * ct_parameters; /* elements are (struct mailmime_parameter *) */
};
struct mailmime_content *
mailmime_content_new(struct mailmime_type * ct_type,
char * ct_subtype,
clist * ct_parameters);
void mailmime_content_free(struct mailmime_content * content);
This is a MIME content type such as message/rfc822 or
text/plain.
ct_type is the main MIME type,
for example text in
plain/text
(see ).
ct_subtype is the MIME subtype,
for example plain in
plain/text.
ct_parameters is the list of parameters for
the given MIME type. For example, for plain/text,
we can find charset=iso-8859-1,
format=flowed. Each element of the list
if of type struct mailmime_parameter *
(see ).
mailmime_content_new() creates and initializes
a data structure with a value.
Structures given as argument are referenced by the created
object and will be freed if the object is released.
mailmime_content_free() frees memory used by
the structure and substructures will also be released.
Creation and display of MIME content type
#include <libetpan/libetpan.h>
int main(void)
{
struct mailmime_content * content;

mm_type. This describes the MIME part type
of this part. The value can be
MAILMIME_SINGLE if this is a single part,
MAILMIME_MULTIPLE if this is a multipart,
MAILMIME_MESSAGE if this is a mesage part.
mm_mime_start. This is used mostly internally.

mailmime_fields (see ) is the native structure
that MIME module will use, this module will provide an easier
structure to use when
parsing fields. mailmime_single_fields is
an easier structure to get parsed fields, rather than
iteration over the list of fields.
fld_content is the MIME content type
(see ).
fld_content_charset is the value
of the MIME type parameter charset.
fld_content_boundary is the value
of the MIME type parameter boundary.
fld_content_name is the value
of the MIME type parameter name.
fld_encoding is the MIME encoding
mechanism used
(see ).
fld_id is the content of the field
Content-ID.
fld_description is the content of the field
Content-Description.
fld_version is the version of MIME
in use.
fld_disposition is the MIME
disposition information
(see ).
fld_disposition_filename is
the filename parameter of the
MIME disposition information.
fld_disposition_creation_date is
the creation-date parameter of the
MIME disposition information.
fld_disposition_modification_date is
the modification-date parameter of the
MIME disposition information.
fld_disposition_read_date is
the read-date parameter of the
MIME disposition information.
fld_disposition_size is
the size parameter of the
MIME disposition information.
fld_language is the language
of the MIME part
(see ).
single_fields is the structure to fill.
fld_fields is the MIME fields list to
use to fill the single_fields.
mailmime_single_fields_new() creates and
initializes a data structure with a

object and will NOT be freed if the
object is released.
mailmime_single_fields_free() frees
memory used by the structure and
substructures will NOT be
released. They should be released by
the application.

Storages, folders, messages
Introduction
This part will give the definition of some objects.
Message
A message is the common e-mail message or news message you
read or send.
MIME part
A message can have attachment such as images or other documents.
The attachment are organized into a tree structure. Each
node of this structure is a MIME part.
Mailbox
A mailbox will contain a given number of messages.
Storage
A storage is a "physical" localisation of your mailbox. This
can be on a filesystem (local or remote disk, this is the
case of MH, mbox and maildir), or this can be on a remote
host (this is the case for POP3, IMAP or NNTP).
Folder
A storage, for the same user, can contain a given number of
mailboxes, depending the storage capabilities, then, the
storage driver capabilities. With etPan!, MH, IMAP and NNTP
storages can have more than one mailbox. The mailboxes will
be called folders. On storage where we only have one
mailbox, the unique mailbox is the unique folder.
Session
The session is the network connection or the entity to which
the commands of the drivers are given.
Error codes
Error codes returned as integers can be one of the following :
enum {
MAIL_NO_ERROR = 0,
MAIL_NO_ERROR_AUTHENTICATED,
MAIL_NO_ERROR_NON_AUTHENTICATED,
MAIL_ERROR_NOT_IMPLEMENTED,

Storage
Storage driver
#include <libetpan/libetpan.h>
typedef struct mailstorage_driver mailstorage_driver;

int (* sto_connect)(struct mailstorage * storage);
int (* sto_get_folder_session)(struct mailstorage * storage,
char * pathname, mailsession ** result);
void (* sto_uninitialize)(struct mailstorage * storage);
};
This is the driver for a storage.
sto_name is the name of the driver.
sto_connect() connects the storage to
the remote access or to the path in the local filesystem.
sto_get_folder_session() can have two
kinds of behaviour. Either it creates a new session and
independant from the session used by the storage and
select the given mailbox or it selects the given mailbox
in the current session. It depends on the efficiency of
the mail access.
XXX - in the future, this will be moved to the
folder driver
sto_uninitialize() frees the data
created with mailstorage constructor.
Storage
#include <libetpan/libetpan.h>
struct mailstorage {
char * sto_id;
void * sto_data;
mailsession * sto_session;
mailstorage_driver * sto_driver;
clist * sto_shared_folders; /* list of (struct mailfolder *) */
void * sto_user_data;
};
sto_id is an identifier for the
storage. This can be NULL.
sto_data is the internal data
of the storage. This can only be changed by the driver.
sto_session is the session used by
the storage. The session can be used to send commands.
sto_driver is the driver of the
storage.
sto_shared_folders is the list of
folders that share the session with the storage.
This is used internally.
sto_user_data is a field for free
use. The user can store any data in that field.
mailstorage_new and mailstorage_free
#include <libetpan/libetpan.h>
struct mailstorage * mailstorage_new(char * sto_id);
void mailstorage_free(struct mailstorage * storage);
mailstorage_new() initializes a storage
structure with an identifier (sto_id) and
with no driver.
mailstorage_free() free the memory used
by a storage.
mailstorage_connect and mailstorage_disconnect
#include <libetpan/libetpan.h>
int mailstorage_connect(struct mailstorage * storage);
void mailstorage_disconnect(struct mailstorage * storage);
mailstorage_connect() connects the storage.
This function can also be used to confirm that a storage
connection is valid when the storage is already connected.
mailstorage_disconnect() disconnects the
storage.
IMAP storage
int imap_mailstorage_init(struct mailstorage * storage,
char * imap_servername, uint16_t imap_port,
char * imap_command,
int imap_connection_type, int imap_auth_type,
char * imap_login, char * imap_password,
int imap_cached, char * imap_cache_directory);
Example
use of storage
int main(void)
{
struct mailstorage * storage;
int r;
storage = mailstorage_new(NULL);
imap_mailstorage_init(storage, "imap.my-servers.org", 0,
NULL, CONNECTION_TYPE_TRY_STARTTLS, IMAP_AUTH_TYPE_PLAIN,
"my-login", "my-password", 1, "/home/login/.libetpan/cache");
r = mailstorage_connect(storage);
if (r == MAIL_NO_ERROR) {
mailstorage_disconnect(storage);
}
mailstorage_free(storage);
}
Folder

int (* fld_noop)(struct mailfolder * folder);
int (* fld_check)(struct mailfolder * folder);
int (* fld_expunge)(struct mailfolder * folder);
int (* fld_status)(struct mailfolder * folder,

};
This is a driver for a session.
sess_name is the name of the driver.
sess_initialize() is the function
that will initializes a data structure (field
sess_data in the session) specific to
the driver.
The field data (field sess_data in
the session) is the state of the session,
the internal data structure used by the driver.
It is called when creating the
mailsession structure with
mailsession_new().
sess_uninitialize() frees the structure
created with sess_initialize()
sess_parameters() implements
functions specific to the given mail access.
sess_connect_stream() connects a
stream to the session.
sess_connect_path() notify a main
path to the session.
sess_starttls() changes the current
stream to a TLS stream
(see ).
sess_login() notifies the user and
the password to authenticate to the session.
sess_logout() exits the session and
closes the stream.
sess_noop() does no operation on the
session, but it can be used to poll for the status of
the connection.
sess_build_folder_name() will return an
allocated string with that contains the complete path of
the folder to create.
Use of this method is deprecated.
sess_create_folder() creates the
folder that corresponds to the given name.
Use of this method is deprecated.
sess_delete_folder() deletes the folder
that corresponds to the given name.
Use of this method is deprecated.
sess_rename_folder() change the name
of the folder.
Use of this method is deprecated.
sess_check_folder() makes a
checkpoint of the session.
sess_examine_folder() selects a mailbox as
readonly.
Use of this method is deprecated.
sess_select_folder() selects a mailbox.
sess_expunge_folder() deletes all
messages marked \Deleted.
sess_status_folder() queries the
status of the folder (number of messages, number of
recent messages, number of unseen messages).
sess_messages_number() queries the
number of messages in the folder.
sess_recent_number() queries the
number of recent messages in the folder.
sess_unseen_number() queries the number of
unseen messages in the folder.
sess_list_folders() returns the list of
all sub-mailboxes of the given mailbox.
Use of this method is deprecated.
sess_lsub_folders() returns the list of
subscribed sub-mailboxes of the given mailbox.
Use of this method is deprecated.
sess_subscribe_folder() subscribes to
the given mailbox.
Use of this method is deprecated.
sess_unsubscribe_folder() unsubscribes to
the given mailbox.
Use of this method is deprecated.
sess_append_message() adds a RFC 2822
message to the current given mailbox.
sess_copy_message() copies a message
whose number is given to a given mailbox. The mailbox
must be accessible from the same session.
Use of this method is deprecated.
sess_move_message() moves a message whose
number is given to
a given mailbox. The mailbox must be accessible from the
same session.
Use of this method is deprecated.
sess_get_messages_list() returns the list
of message numbers
of the current mailbox
(see ).
sess_get_envelopes_list() fills the parsed
fields in the mailmessage structures
(see )
of the mailmessage_list
(see ).
sess_remove_message() removes the given
message from the mailbox.
The message is permanently deleted.
Use of this method is deprecated.
sess_get_message() returns a
mailmessage structure
(see )
that corresponds
to the given message number.
Use of this method is deprecated.
sess_get_message_by_uid() returns a
mailmessage structure
(see )
that corresponds
to the given message unique identifier.
mandatory functions are the following :
sess_connect_stream() or
connect_path()
sess_logout()
sess_get_messages_list()
sess_get_envelopes_list()
we advise you to implement these functions :
sess_select_folder() (in case a session
can access several folders).
sess_noop() (to check if the server is
responding)
sess_check_folder() (to make a checkpoint
of the session)
sess_status_folder(),
sess_messages_number(),
sess_recent_number(),
sess_unseen_number()
(to get stat of the folder)
sess_append_message() (but can't be done
in the case of POP3 at least).
sess_login() in a case of an
authenticated driver.
sess_starttls() in a case of a stream
driver, if the procotol supports STARTTLS.
sess_get_message_by_uid() so that the
application can remember the messages
by UID and build its own list of messages.
Everything that is specific to the driver will be
implemented in sess_parameters().
Session
#include <libetpan/libetpan.h>
struct mailsession {
void * sess_data;
mailsession_driver * sess_driver;
};

int id, void * value);
This function make calls specific to the driver
mailsession_connect_stream
#include <libetpan/libetpan.h>
int mailsession_connect_stream(mailsession * session, mailstream * s);
There are drivers of two kinds : stream drivers (driver that
connects to servers through TCP or other means of connection)
and file drivers (driver that are based on filesystem)
This function can only be used by stream drivers and
this connects a stream to the session
mailsession_connect_path
#include <libetpan/libetpan.h>
