gnutls_credentials_set - Man Page

API function


#include <gnutls/gnutls.h>

int gnutls_credentials_set(gnutls_session_t session, gnutls_credentials_type_t type, void * cred);


gnutls_session_t session

is a gnutls_session_t type.

gnutls_credentials_type_t type

is the type of the credentials

void * cred

the credentials to set


Sets the needed credentials for the specified type.  E.g. username, password - or public and private keys etc.  The  cred parameter is a structure that depends on the specified type and on the current session (client or server).

In order to minimize memory usage, and share credentials between several threads gnutls keeps a pointer to cred, and not the whole cred structure.  Thus you will have to keep the structure allocated until you call gnutls_deinit().

For GNUTLS_CRD_ANON,  cred should be gnutls_anon_client_credentials_t in case of a client.  In case of a server it should be gnutls_anon_server_credentials_t.

For GNUTLS_CRD_SRP,  cred should be gnutls_srp_client_credentials_t in case of a client, and gnutls_srp_server_credentials_t, in case of a server.

For GNUTLS_CRD_CERTIFICATE,  cred should be gnutls_certificate_credentials_t.


On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code is returned.
