sl@0: * Description:
sl@0: * The reentrant system calls here serve two purposes:
sl@0: * 1) Provide reentrant versions of the system calls the ANSI C library
sl@0: * requires.
sl@0: * 2) Provide these system calls in a namespace clean way.
sl@0: * It is intended that *all* system calls that the ANSI C library needs
sl@0: * be declared here.  It documents them all in one place.  All library access
sl@0: * to the system is via some form of these functions.
sl@0: * There are three ways a target may provide the needed syscalls.
sl@0: * 1) Define the reentrant versions of the syscalls directly.
sl@0: * (eg: _open_r, _close_r, etc.).  Please keep the namespace clean.
sl@0: * When you do this, set "syscall_dir" to "syscalls" in configure.in,
sl@0: * and add -DREENTRANT_SYSCALLS_PROVIDED to target_cflags in configure.in.
sl@0: * 2) Define namespace clean versions of the system calls by prefixing
sl@0: * them with '_' (eg: _open, _close, etc.).  Technically, there won't be
sl@0: * true reentrancy at the syscall level, but the library will be namespace
sl@0: * clean.
sl@0: * When you do this, set "syscall_dir" to "syscalls" in configure.in.
sl@0: * 3) Define or otherwise provide the regular versions of the syscalls
sl@0: * (eg: open, close, etc.).  The library won't be reentrant nor namespace
sl@0: * clean, but at least it will work.
sl@0: * When you do this, add -DMISSING_SYSCALL_NAMES to target_cflags in
sl@0: * configure.in.
sl@0: * Stubs of the reentrant versions of the syscalls exist in the libc/reent
sl@0: * source directory and are used if REENTRANT_SYSCALLS_PROVIDED isn't defined.
sl@0: * They use the native system calls: _open, _close, etc. if they're available
sl@0: * (MISSING_SYSCALL_NAMES is *not* defined), otherwise open, close, etc.
sl@0: * (MISSING_SYSCALL_NAMES *is* defined).
sl@0: * WARNING: All identifiers here must begin with an underscore.  This file is
sl@0: * included by stdio.h and others and we therefore must only use identifiers
sl@0: * in the namespace allotted to us.
