NAME
       gnutls_x509_ext_import_name_constraints - API function


SYNOPSIS
       #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
       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
       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
       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
