NAME
       gnutls_x509_crt_get_extension_data - Get the specified extension data

SYNOPSIS
       #include <gnutls/x509.h>

       int gnutls_x509_crt_get_extension_data(gnutls_x509_crt_t cert, int indx, void * data, size_t * sizeof_data);

ARGUMENTS
       gnutls_x509_crt_t cert
		   should contain a gnutls_x509_crt_t structure

       int indx    Specifies which extension OID to send. Use zero to get the first one.

       void * data a pointer to a structure to hold the data (may be null)

       size_t * sizeof_data
		   initially holds the size of oid

DESCRIPTION
       This  function  will return the requested extension data in the certificate.  The extension data will be stored as a string in the provided
       buffer.

       Use gnutls_x509_crt_get_extension_info() to extract the OID and critical flag.  Use gnutls_x509_crt_get_extension_by_oid() instead, if  you
       want to get data indexed by the extension OID rather than sequence.

RETURNS
       On  success,  GNUTLS_E_SUCCESS  (zero)  is returned, otherwise an error code is returned.  If you have reached the last extension available
       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
