The docs state the following :
==========================
msgctl ID, CMD, ARG
Calls the System V IPC function msgctl(2). You'll probably have to say
use IPC::SysV;
first to get the correct constant definitions. If CMD is IPC_STAT, then
ARG must be a variable which will hold the returned msqid_ds structure.
Returns like ioctl: the undefined value for error, "0 but true" for
zero, or the actual return value otherwise. See also perlipc/"SysV IPC",
IPC::SysV, and IPC::Semaphore documentation.
==========================
I have not found a way to dereference the msq_ds array returned as
per
http://cpansearch.bulknews.net/markup/IPC_SysV/SysV.pm. How is this
msqid_ds structure parsed? Do you have a short example?
Thanks,
Eric
