NAME
       libdoor - doors library

SYNOPSIS
       cc [ flag... ] file...  [ library... ]
       #include <door.h>

DESCRIPTION
       Historically,  functions  in  this library provided programmatic access to doors, including the ability to create and call them. This func-
       tionality now resides in libc(3LIB).

       Doors are a fast light-weight RPC mechanism for secure control transfer between processes on the same machine. Conceptually,  a	thread	in
       one  process  can issue a call using a door descriptor that causes code to be executed in another process and then returns using the tradi-
       tional synchronous RPC model.  Doors can also be used to pass data and file descriptors between processes.

       This library is maintained to provide backward compatibility for both runtime and compilation environments. The	shared	object	is  imple-
       mented as a filter on libc.so.1. New application development need not specify -ldoor.
