gnutls_x509_ext_import_name_constraints - API function
#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);
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
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.
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.
