- doors library
cc [ flag... ] file... -ldoor [ library... ] #include <door.h>
The functions in this library provide programmatic access to doors, including the ability to create and call them. 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.
The shared object libdoor.so.1 provides the public interfaces defined below. See Intro(3) for additional information on shared object interfaces.
