SOCKIO(4I) Ioctl Requests SOCKIO(4I)
NAME
sockio - ioctls that operate directly on sockets
SYNOPSIS
#include <sys/sockio.h>DESCRIPTION
The
ioctls listed in this manual page apply directly to sockets,
independent of any underlying protocol. The
setsockopt(3SOCKET) call
(see
getsockopt(3SOCKET)) is the primary method for operating on
sockets, 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. The argument
must be either positive (in which case it must be a
process
ID) or negative (in which case it must be a
process group).
SIOCGPGRP The argument is a pointer to an
int. Get 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(2) points to a mark
in the data stream for an out-of-band message. Set the
value of that
int to
0 if the read pointer for the socket
referred to by the descriptor passed to
ioctl does not
point to a mark in the data stream for an out-of-band
message.
