NAME¶
io_receivefd - receive a file descriptor over a Unix Domain socket
SYNTAX¶
#include <io.h>
int64
io_receivefd(int64 sock);
DESCRIPTION¶
io_receivefd receives a file descriptor from the Unix Domain socket
sock.
You can send a descriptor using
io_passfd(3).
io_receivefd returns -1 on error or the file descriptor.
The underlying Unix API can send more than one descriptor at the time. This
function expects only one descriptor and will return the first one if more
than one were sent.
