gnutls_certificate_server_set_retrieve_function: API function


gnutls_certificate_server_set_retrieve_function - API function


#include <gnutls/compat.h>

void gnutls_certificate_server_set_retrieve_function(gnutls_certificate_credentials_t cred, gnutls_certificate_server_retrieve_function * func);


gnutls_certificate_credentials_t cred
is a gnutls_certificate_credentials_t structure.
gnutls_certificate_server_retrieve_function * func
is the callback function


This function sets a callback to be called in order to retrieve the certificate to be used in the handshake. You are advised to use gnutls_certificate_set_retrieve_function2() because it is much more efficient in the processing it requires from gnutls.

The callback's function prototype is: int (*callback)(gnutls_session_t, gnutls_retr_st* st);

 st should contain the certificates and private keys.

If the callback function is provided then gnutls will call it, in the handshake, after the certificate request message has been received.

The callback function should set the certificate list to be sent, and return 0 on success. The value (-1) indicates error and the handshake will be terminated.
