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 structure.

       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
