.SH NAME
gnutls_srtp_get_keys \- API function
.SH SYNOPSIS
.B #include <gnutls/gnutls.h>
.sp
.BI "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 ");"
.SH ARGUMENTS
.IP "gnutls_session_t session" 12
is a \fBgnutls_session_t\fP type.
.IP "void * key_material" 12
Space to hold the generated key material
.IP "unsigned int key_material_size" 12
The maximum size of the key material
.IP "gnutls_datum_t * client_key" 12
The master client write key, pointing inside the key material
.IP "gnutls_datum_t * client_salt" 12
The master client write salt, pointing inside the key material
.IP "gnutls_datum_t * server_key" 12
The master server write key, pointing inside the key material
.IP "gnutls_datum_t * server_salt" 12
The master server write salt, pointing inside the key material
.SH "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 \fIclient_key\fP , \fIclient_salt\fP , \fIserver_key\fP and \fIserver_salt\fP are convenience datums that point inside the key material. They may
be \fBNULL\fP.
.SH "RETURNS"
On success the size of the key material is returned,
otherwise, \fBGNUTLS_E_SHORT_MEMORY_BUFFER\fP if the buffer given is not
sufficient, or a negative error code.
Since 3.1.4
