LIBDOOR(3LIB) Interface Libraries LIBDOOR(3LIB)

libdoor - doors library

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

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 New application development need not specify -ldoor.

The shared object provides the public interfaces defined below. See Intro(3) for additional information on shared object interfaces.
