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