gnutls_x509_ext_import_name_constraints(3)
NAME
gnutls_x509_ext_import_name_constraints - API function
SYNOPSIS
#include <gnutls/x509-ext.h>
gnutls_x509_ext_import_name_constraints(3) 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 con-
straints 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 fol-
lowing 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
