NAME         top

       gnutls_ocsp_req_get_extension - API function

SYNOPSIS         top

       #include <gnutls/ocsp.h>

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

ARGUMENTS         top

       gnutls_ocsp_req_const_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         top

       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.

       Since 3.7.0  oid ->size does not account for the terminating null
       byte.

RETURNS         top

       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.
