NAME
libdoor - doors library
SYNOPSIS
cc [

library... ]
#include <
door.h>
DESCRIPTION
Historically, functions in this library provided programmatic 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 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
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 application development need not specify
-ldoor.
INTERFACES

libdoor.so.1 provides the public interfaces defined
below. See
