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  functional‐
       ity 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 traditional syn‐
       chronous  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 application development need not  specify
       -ldoor.

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