*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.*****/
