NAME
       gnutls_x509_crt_get_extension_data - API function

SYNOPSIS
       #include <gnutls/x509.h>

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

ARGUMENTS
       gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t type

       unsigned indx
                   Specifies which extension OID to send. Use (0) 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  data

DESCRIPTION
       This function will return the requested extension data in the
       certificate.  The extension data will be stored 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 (0) is returned, otherwise a negative error
       code is returned.  If you have reached the last extension available
       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
