gnutls_x509_crt_get_tlsfeatures - API function
int gnutls_x509_crt_get_tlsfeatures(gnutls_x509_crt_t crt,
gnutls_x509_tlsfeatures_t features, unsigned int
flags, unsigned int * critical);
- 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
- unsigned int flags
- zero or GNUTLS_EXT_FLAG_APPEND
- unsigned int * critical
- the extension status
This function will get the X.509 TLS features extension structure from the
certificate. The returned structure needs to be freed using
When the flags
is set to GNUTLS_EXT_FLAG_APPEND
, then if the
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.
On success, GNUTLS_E_SUCCESS
(0) is returned, otherwise a negative error
