- msgrcv ID,VAR,SIZE,TYPE,FLAGS
-
Calls the System V IPC function msgrcv to receive a message from
message queue ID into variable VAR with a maximum message size of
SIZE. Note that when a message is received, the message type as a
native long integer will be the first thing in VAR, followed by the
actual message. This packing may be opened with
unpack("l! a*").
Taints the variable. Returns true if successful, or false if there is
an error. See also perlipc/"SysV IPC", IPC::SysV, and
IPC::SysV::Msg documentation.
