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.
