NAME

gnutls_x509_crt_get_name_constraints - API function

SYNOPSIS

#include <gnutls/x509.h>

int gnutls_x509_crt_get_name_constraints(gnutls_x509_crt_t crt, gnutls_x509_name_constraints_t nc, unsigned int flags, unsigned int * critical);

ARGUMENTS

should contain a gnutls_x509_crt_t structure
The nameconstraints intermediate structure
zero or GNUTLS_NAME_CONSTRAINTS_FLAG_APPEND
the extension status

DESCRIPTION

This function will return an intermediate structure containing the name constraints of the provided CA certificate. 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
