io_passfd(3)		    Library Functions Manual		    io_passfd(3)

NAME
     io_passfd - pass a file descriptor over a Unix Domain socket

SYNTAX
     #include <libowfat/io.h>

     int io_passfd(int64 sock,int64 fd);

DESCRIPTION
     io_passfd	transfers  the	file  descriptor  fd over the Unix Domain socket
     sock.  This works much like dup(2), only that the copy  of  the  descriptor
     appears  not in this process but at the other end of the Unix Domain socket
     (which therefore must be a process on the same system).

     The peer can then use io_receivefd(3) to receive the file descriptor.

     Note that the passed descriptor stays open in the sending process.

RETURN VALUE
     io_passfd returns 0 on success, -1 on error (setting errno accordingly).

SEE ALSO
     io_receivefd(3)
