NAME
gnutls_x509_crt_get_tlsfeatures - API function
SYNOPSIS
#include <gnutls/x509.h>
gnutls_x509_crt_get_tlsfeatures(3) 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.
SINCE
3.5.1
