* Description:
|
|
sl@0
|
15 |
* The reentrant system calls here serve two purposes:
|
|
sl@0
|
16 |
* 1) Provide reentrant versions of the system calls the ANSI C library
|
|
sl@0
|
17 |
* requires.
|
|
sl@0
|
18 |
* 2) Provide these system calls in a namespace clean way.
|
|
sl@0
|
19 |
* It is intended that *all* system calls that the ANSI C library needs
|
|
sl@0
|
20 |
* be declared here. It documents them all in one place. All library access
|
|
sl@0
|
21 |
* to the system is via some form of these functions.
|
|
sl@0
|
22 |
* There are three ways a target may provide the needed syscalls.
|
|
sl@0
|
23 |
* 1) Define the reentrant versions of the syscalls directly.
|
|
sl@0
|
24 |
* (eg: _open_r, _close_r, etc.). Please keep the namespace clean.
|
|
sl@0
|
25 |
* When you do this, set "syscall_dir" to "syscalls" in configure.in,
|
|
sl@0
|
26 |
* and add -DREENTRANT_SYSCALLS_PROVIDED to target_cflags in configure.in.
|
|
sl@0
|
27 |
* 2) Define namespace clean versions of the system calls by prefixing
|
|
sl@0
|
28 |
* them with '_' (eg: _open, _close, etc.). Technically, there won't be
|
|
sl@0
|
29 |
* true reentrancy at the syscall level, but the library will be namespace
|
|
sl@0
|
30 |
* clean.
|
|
sl@0
|
31 |
* When you do this, set "syscall_dir" to "syscalls" in configure.in.
|
|
sl@0
|
32 |
* 3) Define or otherwise provide the regular versions of the syscalls
|
|
sl@0
|
33 |
* (eg: open, close, etc.). The library won't be reentrant nor namespace
|
|
sl@0
|
34 |
* clean, but at least it will work.
|
|
sl@0
|
35 |
* When you do this, add -DMISSING_SYSCALL_NAMES to target_cflags in
|
|
sl@0
|
36 |
* configure.in.
|
|
sl@0
|
37 |
* Stubs of the reentrant versions of the syscalls exist in the libc/reent
|
|
sl@0
|
38 |
* source directory and are used if REENTRANT_SYSCALLS_PROVIDED isn't defined.
|
|
sl@0
|
39 |
* They use the native system calls: _open, _close, etc. if they're available
|
|
sl@0
|
40 |
* (MISSING_SYSCALL_NAMES is *not* defined), otherwise open, close, etc.
|
|
sl@0
|
41 |
* (MISSING_SYSCALL_NAMES *is* defined).
|
|
sl@0
|
42 |
* WARNING: All identifiers here must begin with an underscore. This file is
|
|
sl@0
|
43 |
* included by stdio.h and others and we therefore must only use identifiers
|
|
sl@0
|
44 |
* in the namespace allotted to us.
