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.
