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
