#include <gnutls/gnutls.h>

void gnutls_certificate_set_verify_function(gnutls_certificate_credentials_t cred, gnutls_certificate_verify_function * func);

is a gnutls_certificate_credentials_t type.
is the callback function

This function sets a callback to be called when peer's certificate has been received in order to verify it on receipt rather than doing after the handshake is completed.

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

If the callback function is provided then gnutls will call it, in the handshake, just after the certificate message has been received. To verify or obtain the certificate the gnutls_certificate_verify_peers2(), gnutls_certificate_type_get(), gnutls_certificate_get_peers() functions can be used.

The callback function should return 0 for the handshake to continue or non-zero to terminate.
