.SH SYNOPSIS
.B #include <gnutls/gnutls.h>
.sp
.BI "int gnutls_session_ext_register(gnutls_session_t " session ", const char * " name ", int " type ", gnutls_ext_parse_type_t " parse_type ", gnutls_ext_recv_func " recv_func ", gnutls_ext_send_func " send_func ", gnutls_ext_deinit_data_func " deinit_func ", gnutls_ext_pack_func " pack_func ", gnutls_ext_unpack_func " unpack_func ", unsigned " flags ");"
.SH ARGUMENTS
.IP "gnutls_session_t session" 12
the session for which this extension will be set
.IP "const char * name" 12
the name of the extension to register
.IP "int type" 12
the numeric id of the extension
.IP "gnutls_ext_parse_type_t parse_type" 12
the parse type of the extension (see gnutls_ext_parse_type_t)
.IP "gnutls_ext_recv_func recv_func" 12
a function to receive the data
.IP "gnutls_ext_send_func send_func" 12
a function to send the data
.IP "gnutls_ext_deinit_data_func deinit_func" 12
a function deinitialize any private data
.IP "gnutls_ext_pack_func pack_func" 12
a function which serializes the extension's private data (used on session packing for resumption)
.IP "gnutls_ext_unpack_func unpack_func" 12
a function which will deserialize the extension's private data
.IP "unsigned flags" 12
must be zero
.SH "DESCRIPTION"
This function will register a new extension type. The extension will be
only usable within the registered session. If the extension type
is already registered then \fBGNUTLS_E_ALREADY_REGISTERED\fP will be returned.

Each registered extension can store temporary data into the gnutls_session_t
structure using \fBgnutls_ext_set_data()\fP, and they can be retrieved using
\fBgnutls_ext_get_data()\fP.
.SH "RETURNS"
\fBGNUTLS_E_SUCCESS\fP on success, otherwise a negative error code.
