IPC::Msg - SysV Msg IPC object class
use IPC::SysV qw(IPC_PRIVATE S_IRUSR S_IWUSR); use IPC::Msg; $msg = IPC::Msg->new(IPC_PRIVATE, S_IRUSR | S_IWUSR); $msg->snd($msgtype, $msgdata); $msg->rcv($buf, 256); $ds = $msg->stat; $msg->remove;
A class providing an object based interface to SysV IPC message queues.
On creation of a new message queue "FLAGS" is used to set the permissions. Be careful not to set any flags that the Sys V IPC implementation does not allow: in some systems setting execute bits makes the operations fail.
uid gid mode (oly the permission bits) qbytes
"set" accepts either a stat object, as returned by the "stat" method, or a list of name-value pairs.
uid gid cuid cgid mode qnum qbytes lspid lrpid stime rtime ctime
