NAME         top

       gnutls_credentials_set - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

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

ARGUMENTS         top

       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

DESCRIPTION         top

       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

       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

RETURNS         top

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