* Description:
* The reentrant system calls here serve two purposes:
* 1) Provide reentrant versions of the system calls the ANSI C library
* requires.
* 2) Provide these system calls in a namespace clean way.
* It is intended that *all* system calls that the ANSI C library needs
* be declared here. It documents them all in one place. All library access
* to the system is via some form of these functions.
* There are three ways a target may provide the needed syscalls.
* 1) Define the reentrant versions of the syscalls directly.
* (eg: _open_r, _close_r, etc.). Please keep the namespace clean.
* When you do this, set "syscall_dir" to "syscalls" in configure.in,
* and add -DREENTRANT_SYSCALLS_PROVIDED to target_cflags in configure.in.
* 2) Define namespace clean versions of the system calls by prefixing
* them with '_' (eg: _open, _close, etc.). Technically, there won't be
* true reentrancy at the syscall level, but the library will be namespace
* clean.
* When you do this, set "syscall_dir" to "syscalls" in configure.in.
* 3) Define or otherwise provide the regular versions of the syscalls
* (eg: open, close, etc.). The library won't be reentrant nor namespace
* clean, but at least it will work.
* When you do this, add -DMISSING_SYSCALL_NAMES to target_cflags in
* configure.in.
* Stubs of the reentrant versions of the syscalls exist in the libc/reent
* source directory and are used if REENTRANT_SYSCALLS_PROVIDED isn't defined.
* They use the native system calls: _open, _close, etc. if they're available
* (MISSING_SYSCALL_NAMES is *not* defined), otherwise open, close, etc.
* (MISSING_SYSCALL_NAMES *is* defined).
* WARNING: All identifiers here must begin with an underscore. This file is
* included by stdio.h and others and we therefore must only use identifiers
* in the namespace allotted to us.
