API function

Synopsis

#include <gnutls/x509.h>

int gnutls_x509_crt_get_tlsfeatures(gnutls_x509_crt_t crt, gnutls_x509_tlsfeatures_t features, unsigned int flags, unsigned int * critical);

Arguments

gnutls_x509_crt_t crt

A X.509 certificate

gnutls_x509_tlsfeatures_t features

If the function succeeds, the features will be stored in this variable.

unsigned int flags

zero or GNUTLS_EXT_FLAG_APPEND

unsigned int * critical

the extension status

Description

This function will get the X.509 TLS features extension structure from the certificate. The returned structure needs to be freed using gnutls_x509_tlsfeatures_deinit().

When the  flags is set to GNUTLS_EXT_FLAG_APPEND, then if the  features structure is empty this function will behave identically as if the flag was not set. Otherwise if there are elements  in the  features structure then they will be merged with.

Note that  features must be initialized prior to calling this function.

Returns

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
