Hmm interest enough,
But please see man.

NOTES
       On Linux, the only supported domain for this call is AF_UNIX (or
 syn-
       onymously,  AF_LOCAL).   (Most  implementations have the same
restric-
       tion.)

Only for AF_UNIX..

If linux want to be adopted on mission critical world, this function is
esseintial.
