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?
