// This module contains bindings to the native Haiku API. The Haiku API
// originates from BeOS, and it was the original way to perform low level
// system and IO operations. The POSIX API was in that era was like a
// compatibility layer. In current Haiku development, both the POSIX API and
// the Haiku API are considered to be co-equal status. However, they are not
// integrated like they are on other UNIX platforms, which means that for many
// low level concepts there are two versions, like processes (POSIX) and
// teams (Haiku), or pthreads and native threads.
//
// Both the POSIX API and the Haiku API live in libroot.so, the library that is
// linked to any binary by default.
//
// This file follows the Haiku API for Haiku R1 beta 2. It is organized by the
// C/C++ header files in which the concepts can be found, while adhering to the
// style guide for this crate.

// Helper macro to generate u32 constants. The Haiku API uses (non-standard)
// multi-character constants (like 'UPDA' or 'MSGM') to represent 32 bit
// integer constants.
