/***
*process.h - definition and declarations for process control functions
*
*	Copyright (c) 1985-1993, Microsoft Corporation. All rights reserved.
*
*Purpose:
*	This file defines the modeflag values for spawnxx calls.
*	Only P_WAIT and P_OVERLAY are currently implemented on MS-DOS.
*	Also contains the function argument declarations for all
*	process control related routines.
*
*Revision History:
*	08/24/87  JCR	Added P_NOWAITO
*	10/20/87  JCR	Removed "MSC40_ONLY" entries and "MSSDK_ONLY" comments
*	12-11-87  JCR	Added "_loadds" functionality
*	12-18-87  JCR	Added _FAR_ to declarations
*	01-11-88  JCR	Added _beginthread/_endthread
*	01-15-88  JCR	Got rid of _p_overlay for MTRHEAD/DLL
*	02-10-88  JCR	Cleaned up white space
*	05-08-88  SKS	Removed bogus comment about "DOS 4"; Added "P_DETACH"
*	08-22-88  GJF	Modified to also work for the 386 (small model only)
*	09-14-88  JCR	Added _cexit and _c_exit declarations
*	05-03-89  JCR	Added _INTERNAL_IFSTRIP for relinc usage
*	06-08-89  JCR	386 _beginthread does NOT take a stackpointer arg
*	08-01-89  GJF	Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model)
*	10-30-89  GJF	Fixed copyright
*	11-02-89  JCR	Changed "DLL" to "_DLL"
*	11-17-89  GJF	Added const attribute to appropriate arg types
*	03-01-90  GJF	Added #ifndef _INC_PROCESS and #include <cruntime.h>
*			stuff. Also, removed some (now) useless preprocessor
*			directives.
*	03-21-90  GJF	Replaced _cdecl with _CALLTYPE1 or _CALLTYPE2 in
*			prototypes.
*	04-10-90  GJF	Replaced remaining instances of _cdecl (with _CALLTYPE1
*			or _VARTYPE1, as appropriate).
*	10-12-90  GJF	Changed return type of _beginthread() to unsigned long.
*	01-17-91  GJF	ANSI naming.
*	08-20-91  JCR	C++ and ANSI naming
*	08-26-91  BWM	Added prototypes for _loaddll, unloaddll, and
*			_getdllprocaddr.
*	09-28-91  JCR	ANSI names: DOSX32=prototypes, WIN32=#defines for now
*	07-22-92  GJF	Deleted references to _wait for Win32.
*	08-05-92  GJF	Function calling type and variable type macros.
*	08-28-92  GJF	#ifdef-ed out for POSIX.
*	09-03-92  GJF	Merged two changes above.
*	01-21-93  GJF	Removed support for C6-386's _cdecl.
