This RPC library routine exists in IRIX libc but is not yet fully
implemented. It may be fully implemented in a future version of IRIX.
Until then, use of this routine by applications is unsupported.
If a third-party library uses this function to enable multi-threaded RPC,
you should use the following code to disable the feature. This code
should run after the third-party library's call and before any calls to
_ssss_vvvv_cccc______rrrr_uuuu_nnnn, _ssss_vvvv_cccc______gggg_eeee_tttt_rrrr_eeee_qqqq or _ssss_vvvv_cccc______gggg_eeee_tttt_rrrr_eeee_qqqq_ssss_eeee_tttt.
