NAME
       gnutls_x509_crt_get_tlsfeatures - 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.

SINCE
       3.5.1
