NAME
     gnutls_srtp_get_keys - API function

SYNOPSIS
     #include <gnutls/gnutls.h>

     int gnutls_srtp_get_keys(gnutls_session_t session, void * key_material, un-
     signed 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
     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
     This is a helper function to generate the keying material for SRTP.  It re-
     quires  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
