*crt0dat.c - 32-bit C run-time initialization/termination routines
*
* Copyright (c) 1986-1997, Microsoft Corporation. All rights reserved.
*
*Purpose:
* This module contains the routines _cinit, exit, and _exit
* for C run-time startup and termination. _cinit and exit
* are called from the _astart code in crt0.asm.
* This module also defines several data variables used by the
* runtime.
*
* [NOTE: Lock segment definitions are at end of module.]
*
* *** FLOATING POINT INITIALIZATION AND TERMINATION ARE NOT ***
* *** YET IMPLEMENTED IN THE MAC VERSION ***

*exit(status), _exit(status), _cexit(void), _c_exit(void) - C termination
*
*Purpose:
*
* Entry points:
*
* exit(code): Performs all the C termination functions
* and terminates the process with the return code
* supplied by the user.
*
* _exit(code): Performs a quick exit routine that does not
* do certain 'high-level' exit processing. The _exit
* routine terminates the process with the return code
* supplied by the user.
*
* _cexit(): Performs the same C lib termination processing
* as exit(code) but returns control to the caller
* when done (i.e., does NOT terminate the process).
*
* _c_exit(): Performs the same C lib termination processing
* as _exit(code) but returns control to the caller
* when done (i.e., does NOT terminate the process).
*
* Termination actions:
*
* exit(), _cexit():
*
* 1. call user's terminator routines
* 2. call C runtime preterminators
*
* _exit(), _c_exit():
*
* 3. call C runtime terminators
* 4. return to DOS or caller
*
* Notes:
*
* The termination sequence is complicated due to the multiple entry
* points sharing the common code body while having different entry/exit
* sequences.
*
* Multi-thread notes:
*
* 1. exit() should NEVER be called when mthread locks are held.
* The exit() routine can make calls that try to get mthread locks.
*
* 2. _exit()/_c_exit() can be called from anywhere, with or without locks held.
* Thus, _exit() can NEVER try to get locks (otherwise, deadlock
* may occur). _exit() should always 'work' (i.e., the process
* should always terminate successfully).
*
* 3. Only one thread is allowed into the exit code (see _lockexit()
* and _unlockexit() routines).
*
*Entry:
* exit(), _exit()
* int status - exit status (0-255)

*
* Since _exit() must ALWAYS be able to work (i.e., can be called
* from anywhere with no regard for locking), we must make sure the
* program does not deadlock at step (d) above.
*
* (2) If a thread executing exit() or _exit() aquires the exit lock,
* other threads trying to get the lock will pend forever. That is,
* since exit() and _exit() terminate the process, there is not need
* for them to unlock the exit code path.
*
* (3) Note that onexit()/atexit() routines call _lockexit/_unlockexit
* to protect mthread access to the onexit table.
*
* (4) The 32-bit OS semaphore calls DO allow a single thread to acquire
* the same lock multiple times* thus, this version is straight forward.
