msgrcv

  • 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 SysV IPC in perlipc, IPC::SysV , and IPC::SysV::Msg documentation.
