// globals.h - global variables/needed across modules

// Copyright (c) 1988-1990, Microsoft Corporation. All rights reserved.
|
||
|
|
//
|
||
|
|
// Purpose:
|
||
|
|
// Globals.c is the routine in which global variables reside. Globals.h mirrors
|
||
|
|
// the declarations in globals.c as externs and is included in all routines that
|
||
|
|
// use globals.
|
||
|
|
//
|
||
|
|
// Notes:
|
||
|
|
// This module was created for an interesting reason. NMAKE handles recursive
|
||
|
|
// calls by saving its global variables somewhere in memory. It handles this by
|
||
|
|
// allocating all global variables which have value changes in each recursive
|
||
|
|
// in adjacent memory. The routine called recursively is doMake() and before it
|
||
|
|
// is called the address of this chunk of memory is stored. When the recursive
|
||
|
|
// call returns the memory is restored using the stored address. startOfSave and
|
||
|
|
// endOfSave give the location of this chunk. The reason this method was opted
|
||
|
|
// for is that spawning of NMAKE would consume a lot of memory under DOS. This
|
||
|
|
// might not be very efficient under OS/2 because the code gets shared.
|
||
|
|
//
|
||
|
|
// Revision History:
|
||
|
|
// 15-Nov-1993 JdR Major speed improvements
|
||
|
|
// 04-Apr-1990 SB Add fHeapChk
|
||
|
|
// 01-Dec-1989 SB Made some variables near and pushed some into saveArea
|
||
|
|
// 19-Oct-1989 SB variable fOptionK added (ifdef SLASHK)
|
||
|
|
// 02-Oct-1989 SB add dynamic inline file handling support
|
||
|
|
// 24-Apr-1989 SB Added ext_size, filename_size, filenameext_size &
|
||
|
|
// resultbuf_size for OS/2 1.2 support
|
||
|
|
// 05-Apr-1989 SB made revList, delList, scriptFileList NEAR
|
||
|
|
// 22-Mar-1989 SB removed tmpFileStack and related variables
|
||
|
|
// 16-Feb-1989 SB added delList to have scriptfile deletes at end of make
|
||
|
|
// 21-Dec-1988 SB Added scriptFileList to handle multiple script files
|
||
|
|
// removed tmpScriptFile and fKeep (not reqd anymore)
|
||
|
|
// 19-Dec-1988 SB Added fKeep to handle KEEP/NOKEEP
|
||
|
|
// 14-Dec-1988 SB Added tmpScriptFile for 'z' option
|
||
|
|
// 30-Nov-1988 SB Added revList to handle 'z' option
|
||
|
|
// 23-Nov-1988 SB Added CmdLine[] to handle extmake syntax
|
||
|
|
// made pCmdLineCopy Global in build.c
|
||
|
|
// 21-Oct-1988 SB Added fInheritUserEnv to inherit macros
|
||
|
|
// 20-Sep-1988 RB Clean up.
|
||
|
|
// 17-Aug-1988 RB Declare everything NEAR.
|
||
|
|
// 06-Jul-1988 rj Ditched shell and argVector globals.
|
||
|
|
// Put all ECS declarations as macros in here.
