18 is a gnutls_session_t type.

20 void * key_material
21 Space to hold the generated key material
22
23 unsigned int key_material_size
24 The maximum size of the key material
25
26 gnutls_datum_t * client_key
27 The master client write key, pointing inside the key mate‐
28 rial
29
30 gnutls_datum_t * client_salt
31 The master client write salt, pointing inside the key mate‐
32 rial
33
34 gnutls_datum_t * server_key
35 The master server write key, pointing inside the key mate‐
36 rial
37
38 gnutls_datum_t * server_salt
39 The master server write salt, pointing inside the key mate‐
40 rial

43 This is a helper function to generate the keying material for SRTP. It
44 requires the space of the key material to be pre-allocated (should be
45 at least 2x the maximum key size and salt size). The client_key ,
46 client_salt , server_key and server_salt are convenience datums that
47 point inside the key material. They may be NULL.
48
50 On success the size of the key material is returned, otherwise,
51 GNUTLS_E_SHORT_MEMORY_BUFFER if the buffer given is not sufficient, or
52 a negative error code.
