NAME
gnutls_srtp_get_keys - API function
SYNOPSIS
#include <gnutls/gnutls.h>
int gnutls_srtp_get_keys(gnutls_session_t session, void * key_material,
unsigned int key_material_size, gnutls_datum_t * client_key, gnutls_da-
tum_t * client_salt, gnutls_datum_t * server_key, gnutls_datum_t *
server_salt);
ARGUMENTS
gnutls_session_t session
is a gnutls_session_t type.
void * key_material
Space to hold the generated key material
unsigned int key_material_size
The maximum size of the key material
gnutls_datum_t * client_key
The master client write key, pointing inside the key mate-
rial
gnutls_datum_t * client_salt
The master client write salt, pointing inside the key mate-
rial
gnutls_datum_t * server_key
The master server write key, pointing inside the key mate-
rial
gnutls_datum_t * server_salt
The master server write salt, pointing inside the key mate-
rial
DESCRIPTION
This is a helper function to generate the keying material for SRTP. It
requires the space of the key material to be pre-allocated (should be
at least 2x the maximum key size and salt size). The client_key ,
client_salt , server_key and server_salt are convenience datums that
point inside the key material. They may be NULL.
RETURNS
On success the size of the key material is returned, otherwise,
GNUTLS_E_SHORT_MEMORY_BUFFER if the buffer given is not sufficient, or
a negative error code.
Since 3.1.4
