# NAME

msgrcv - receive a SysV IPC message from a message queue

# SYNOPSIS

msgrcv ID,VAR,SIZE,TYPE,FLAGS

# DESCRIPTION

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 the perlipc manpage, `IPC::SysV`, and `IPC::SysV::Msg` documentation.
