NAME         top

       gnutls_x509_ext_import_name_constraints - API function

SYNOPSIS         top

       #include <gnutls/x509-ext.h>

       int gnutls_x509_ext_import_name_constraints(const gnutls_datum_t
       * ext, gnutls_x509_name_constraints_t nc, unsigned int flags);

ARGUMENTS         top

       const gnutls_datum_t * ext
                   a DER encoded extension

       gnutls_x509_name_constraints_t nc
                   The nameconstraints

       unsigned int flags
                   zero or GNUTLS_NAME_CONSTRAINTS_FLAG_APPEND

DESCRIPTION         top

       This function will return an intermediate type containing the
       name constraints of the provided NameConstraints extension. That
       can be used in combination with
       gnutls_x509_name_constraints_check() to verify whether a server's
       name is in accordance with the constraints.

       When the  flags is set to GNUTLS_NAME_CONSTRAINTS_FLAG_APPEND,
       then if the  nc type is empty this function will behave
       identically as if the flag was not set.  Otherwise if there are
       elements in the  nc structure then the constraints will be merged
       with the existing constraints following RFC5280 p6.1.4 (excluded
       constraints will be appended, permitted will be intersected).

       Note that  nc must be initialized prior to calling this function.

RETURNS         top

       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.
