gnutls_credentials_set: API function


gnutls_credentials_set - 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 structure.
gnutls_credentials_type_t type
is the type of the credentials
void * cred
is a pointer to a structure.


Sets the needed credentials for the specified type. Eg 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.
