netreport - request notification of network interface
changes
SYNOPSIS
netreport [-r]
DESCRIPTION
netreport tells the network management scripts to send a
SIGIO signal to the process which called netreport when
any network interface status changes occur.
OPTIONS
-r Remove the current request (if any) for the calling
process.
NOTES
If a program does not call netreport with the -r option
before it exits, and another process is created with the
same PID before any changes take place in interface sta
tus, it is possible that the new process will receive a
spurious SIGIO.
