SYNOPSIS

#include <gnutls/x509.h> int gnutls_x509_name_constraints_get_permitted(gnutls_x509_name_constraints_t nc, unsigned idx, unsigned * type, gnutls_datum_t * name);

That structure can be used in combination with gnutls_x509_name_constraints_check() to verify whether a server's name is in accordance with the constraints. The name should be treated as constant and valid for the lifetime of nc .
