     1 /* This header file provides the reentrancy.  */
     3 /* The reentrant system calls here serve two purposes:
     5    1) Provide reentrant versions of the system calls the ANSI C library
     6       requires.
     7    2) Provide these system calls in a namespace clean way.
     9    It is intended that *all* system calls that the ANSI C library needs
    10    be declared here.  It documents them all in one place.  All library access
    11    to the system is via some form of these functions.
    13    There are three ways a target may provide the needed syscalls.
    15    1) Define the reentrant versions of the syscalls directly.
    16       (eg: _open_r, _close_r, etc.).  Please keep the namespace clean.
    17       When you do this, set "syscall_dir" to "syscalls" in configure.in,
    18       and add -DREENTRANT_SYSCALLS_PROVIDED to target_cflags in configure.in.
    20    2) Define namespace clean versions of the system calls by prefixing
    21       them with '_' (eg: _open, _close, etc.).  Technically, there won't be
    22       true reentrancy at the syscall level, but the library will be namespace
    23       clean.
    24       When you do this, set "syscall_dir" to "syscalls" in configure.in.
    26    3) Define or otherwise provide the regular versions of the syscalls
    27       (eg: open, close, etc.).  The library won't be reentrant nor namespace
    28       clean, but at least it will work.
    29       When you do this, add -DMISSING_SYSCALL_NAMES to target_cflags in
    30       configure.in.
    32    Stubs of the reentrant versions of the syscalls exist in the libc/reent
    33    source directory and are used if REENTRANT_SYSCALLS_PROVIDED isn't defined.
    34    They use the native system calls: _open, _close, etc. if they're available
    35    (MISSING_SYSCALL_NAMES is *not* defined), otherwise open, close, etc.
    36    (MISSING_SYSCALL_NAMES *is* defined).  */
