NAME
     libdoor - doors library

SYNOPSIS
     cc [ flag... ] file...  [ library... ]
     #include 


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


     Doors are a fast light-weight RPC mechanism for secure  con-
     trol transfer between processes on the same machine. Concep-
     tually, 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  traditional  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 implemented as a filter on libc.so.1. New applica-
     tion development need not specify -ldoor.

INTERFACES
     The shared object libdoor.so.1 provides  the  public  inter-
     faces defined below. See Intro(3) for additional information
     on shared object interfaces.
