NAME        top

       gnutls_x509_ext_import_name_constraints - API function

SYNOPSIS        top

#include <gnutls/x509-ext.h>int gnutls_x509_ext_import_name_constraints(const gnutls_datum_t *ext, gnutls_x509_name_constraints_tnc, unsigned intflags);

ARGUMENTS        top

       const gnutls_datum_t * ext                   a DER encoded extension       gnutls_x509_name_constraints_t nc                   The nameconstraints       unsigned int flags                   zero orGNUTLS_NAME_CONSTRAINTS_FLAG_APPEND

DESCRIPTION        top

       This function will return an intermediate type containing the name       constraints of the provided NameConstraints extension. That can be       used in combination withgnutls_x509_name_constraints_check()to       verify whether a server's name is in accordance with the       constraints.       When theflags is set toGNUTLS_NAME_CONSTRAINTS_FLAG_APPEND,       then if thenc type is empty this function will behave       identically as if the flag was not set.  Otherwise if there are       elements in thenc 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 thatnc must be initialized prior to calling this function.

RETURNS        top

       On success,GNUTLS_E_SUCCESS(0) is returned,GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLEif the extension is not       present, otherwise a negative error value.

SINCE        top

       3.3.0
