Api function
Usage
#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 |
unsigned int * critical
|
the extension status |
Overview
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.
