Manual page for SOCKIO(4)
sockio - ioctls that operate directly on sockets
SYNOPSIS
#include <sys/sockio.h>
DESCRIPTION
The
IOCTL's
listed in this manual page apply directly to sockets, independent of any
underlying protocol.
Note: the
setsockopt
system call (see
getsockopt.2
is the primary method for operating on sockets as such, rather
than on the underlying protocol or network interface.
ioctls
for a specific network interface or protocol are documented in the
manual page for that interface or protocol.
- SIOCSPGRP
-
The argument is a pointer to an
int.
Set the process-group ID that will subsequently receive
SIGIO
or
SIGURG
signals for the socket referred to by the descriptor passed to
ioctl
to the value of that
int.
- SIOCGPGRP
-
The argument is a pointer to an
int.
Set the value of that
int
to the process-group
ID
that is receiving
SIGIO
or
SIGURG
signals for the socket referred to by the descriptor passed to
ioctl.
- SIOCCATMARK
-
The argument is a pointer to an
int.
Set the value of that
int
to 1 if the read pointer for the socket referred to by the descriptor passed
to
ioctl
points to a mark in the data stream for an out-of-band message, and to 0 if it
does not point to a mark.
