Re: Passing sockets with "givedescriptor()" (across user profiles)

The last time I discussed this with an IBMer, the recommendation was to stop using givedescriptor/takedescriptor. Off the top of my head, I don't remember their reasoning.

They recommend using the sendmsg/recvmsg routines as a replacement.

Uh, exactly how does one use sendmsg/recvmsg to pass a socket from one job to another? Looking at sendmsg() in the aforementioned 22-year-old manual, I see that it apparently can pass a descriptor through a socket (although it doesn't say anything about how), but how does that help me, given that there isn't a socket connecting the two jobs (the only socket is the one connecting to the client)?
