Detailed Description

Pipes.

Pipes are exposed in the /dev/pipe directory. Pipes are unidirectional communication channels that can be used for inter-process communication (IPC).

Creating Pipes

Pipes are created using the /dev/pipe/new file. Opening this file using open() will return one file descriptor that can be used for both reading and writing. To create a pipe with separate file descriptors for reading and writing, use open2() with the /dev/pipe/new file.

Using Pipes

Pipes can be read from and written to using the expected read() and write() system calls. Pipes are blocking and pollable, following expected POSIX semantics.
