/* This header file provides the reentrancy. */
/* 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. */
