NAME

       gnutls_session_set_verify_function - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       void gnutls_session_set_verify_function(gnutls_session_t session,
       gnutls_certificate_verify_function * func);

ARGUMENTS

       gnutls_session_t session
                   is a gnutls_session_t type.

       gnutls_certificate_verify_function * func
                   is the callback function

DESCRIPTION

       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. This
       overrides any callback set using
       gnutls_certificate_set_verify_function().

       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.
