NAME

       gnutls_x509_name_constraints_get_permitted - API function

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);

ARGUMENTS

       gnutls_x509_name_constraints_t nc
                   the extracted name constraints

       unsigned idx
                   the index of the constraint

       unsigned * type
                   the type of the constraint (of type gnutls_x509_subject_alt_name_t)

       gnutls_datum_t * name
                   the name in the constraint (of the specific type)

DESCRIPTION

       This function will return an intermediate type containing  the  name  constraints  of  the
       provided   CA   certificate.   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 .

RETURNS

       On success, GNUTLS_E_SUCCESS (0) is returned, GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the
       extension is not present, otherwise a negative error value.

SINCE

       3.3.0
