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.
