NAME         top

       gnutls_srtp_get_keys - API function

SYNOPSIS         top

       #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_datum_t * client_salt, gnutls_datum_t *
       server_key, gnutls_datum_t * server_salt);

ARGUMENTS         top

       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
                   material

       gnutls_datum_t * client_salt
                   The master client write salt, pointing inside the key
                   material

       gnutls_datum_t * server_key
                   The master server write key, pointing inside the key
                   material

       gnutls_datum_t * server_salt
                   The master server write salt, pointing inside the key
                   material

DESCRIPTION         top

       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         top

       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
