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 intermediate structure
unsigned int flags
zero or GNUTLS_NAME_CONSTRAINTS_FLAG_APPEND
DESCRIPTION
This function will return an intermediate structure containing the name
constraints of the provided NameConstraints extension. 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.
When the flags is set to GNUTLS_NAME_CONSTRAINTS_FLAG_APPEND, then if
the nc structure is empty this function will behave identically as if
the flag was not set. Otherwise if there are elements in the nc
structure then only the excluded constraints will be appended to the
constraints.
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
