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.
