Re: Getting PID of socket client

follow-up

Seems like at least OpenBSD implemented SO_PEERCRED which returns a struct
sockpeercred.

/* Read using getsockopt() with SOL_SOCKET, SO_PEERCRED */
struct sockpeercred {
uid_t uid; /* effective user id */
gid_t gid; /* effective group id */
pid_t pid;
};

If not anyone is oppose to this or know some other secret API that provides
similar functionality, I can see if I can put together a patch for this
very useful API.
