IPC Protocol Definition Language (IPDL)

IPDL, short for "IPC (Inter-process communication) Protocol Definition Language", is a Mozilla-specific language allowing C++ code to pass messages between processes or threads in an organized and secure way. All messages for multi-process plugins and tabs in Firefox are declared in the IPDL language.
