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_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 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
