gnutls_x509_ext_import_name_constraints(3)

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 type 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
