io_socketpair(3) Library Functions Manual io_socketpair(3)NAME
io_socketpair - create a pair of sockets
SYNTAX
#include <io.h>
int io_socketpair(int64 pfd[2]);
DESCRIPTION
io_socketpair creates a new UNIX socket pair and writes both descriptors to d. The socket pair works much like a pipe, but it is bidirec-
tional (i.e. both descriptors are for reading and writing).
io_socketpair returns 1 to indicate success. If something goes wrong, io_socketpair returns 0, setting errno to indicate the error; in this
case it frees any memory that it allocated for the new socketpair, and it leaves d alone.
