NAME

       gnutls_ocsp_req_get_extension - API function

SYNOPSIS

       #include <gnutls/ocsp.h>

       int  gnutls_ocsp_req_get_extension(gnutls_ocsp_req_t  req, unsigned indx, gnutls_datum_t *
       oid, unsigned int * critical, gnutls_datum_t * data);

ARGUMENTS

       gnutls_ocsp_req_t req
                   should contain a gnutls_ocsp_req_t type

       unsigned indx
                   Specifies which extension OID to get. Use (0) to get the first one.

       gnutls_datum_t * oid
                   will hold newly allocated buffer with OID of extension, may be NULL

       unsigned int * critical
                   output variable with critical flag, may be NULL.

       gnutls_datum_t * data
                   will hold newly allocated buffer with extension data, may be NULL

DESCRIPTION

       This function will return all information  about  the  requested  extension  in  the  OCSP
       request.   The  information  returned  is the OID, the critical flag, and the data itself.
       The extension OID will be stored as a string.  Any of  oid ,  critical , and  data may  be
       NULL which means that the caller is not interested in getting that information back.

       The caller needs to deallocate memory by calling gnutls_free() on
        oid ->data and  data ->data.

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.
