NAME         top

       gnutls_session_set_verify_function - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       void gnutls_session_set_verify_function(gnutls_session_t session,
       gnutls_certificate_verify_function * func);

ARGUMENTS         top

       gnutls_session_t session
                   is a gnutls_session_t type.

       gnutls_certificate_verify_function * func
                   is the callback function

DESCRIPTION         top

       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

       The callback's function prototype is: int

       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_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.
