// UTILB.C -- Data structure manipulation functions specific to OS/2
|
||
|
|
//
|
||
|
|
// Copyright (c) 1988-1990, Microsoft Corporation. All rights reserved.
|
||
|
|
//
|
||
|
|
// Purpose:
|
||
|
|
// This file was created from functions in util.c & esetdrv.c which were system
|
||
|
|
// dependent. This was done so that the build of the project became simpler and
|
||
|
|
// there was a clear flow in the build process.
|
||
|
|
//
|
||
|
|
// Method of Creation:
|
||
|
|
// 1. Identified all functions having mixed mode code.
|
||
|
|
// 2. Deleted all code blocked out by '#ifndef BOUND' preprocessor directives
|
||
|
|
// in these functions
|
||
|
|
// 3. Deleted all local function & their prototypes not referred by these
|
||
|
|
// 4. Deleted all global data unreferenced by these, including data blocked
|
||
|
|
// of by '#ifdef DEBUG'
|
||
|
|
//
|
||
|
|
// Revision History:
|
||
|
|
// 21-Feb-1994 HV Get rid of _alloca in findFirst: it confuses the compiler's
|
||
|
|
// backend scheduler (PhilLu).
|
||
|
|
// 15-Nov-1993 JdR Major speed improvements
|
||
|
|
// 15-Oct-1993 HV Use tchar.h instead of mbstring.h directly, change STR*() to _ftcs*()
|
||
|
|
// 15-Jun-1993 HV No longer display warning about filenames being longer than
|
||
|
|
// 8.3. Decision made by EmerickF, see Ikura bug #86 for more
|
||
|
|
// details.
|
||
|
|
// 03-Jun-1993 HV Fixed findFirst's pathname truncation (Ikura bug #86)
|
||
|
|
// 10-May-1993 HV Add include file mbstring.h
|
||
|
|
// Change the str* functions to STR*
|
||
|
|
// 08-Jun-1992 SS Port to DOSX32
|
||
|
|
// 10-Apr-1990 SB removed if _osmode stuff, not needed in protect only version.
|
||
|
|
// 04-Dec-1989 SB removed unreferenced local variables in findFirst()
|
||
|
|
// 01-Dec-1989 SB changed a remaining free() to FREE(); now FREE()'ing all
|
||
|
|
// allocated stuff from findFirst() on exit
|
||
|
|
// 22-Nov-1989 SB Add #ifdef DEBUG_FIND to debug FIND_FIRST, etc.
|
||
|
|
// 13-Nov-1989 SB Define INCL_NOPM to exclude <pm.h>
|
||
|
|
// 19-Oct-1989 SB findFirst() and findNext() get extra parameter
|
||
|
|
// 08-Oct-1989 SB remove quotes around a name before making system call
|
||
|
|
// 02-Oct-1989 SB setdrive() proto change
|
||
|
|
// 04-Sep-1989 SB Add DOSFINDCLOSE calls is findFirst and QueryFileInfo
|
||
|
|
// 05-Jul-1989 SB add curTime() to get current time. (C Runtime function
|
||
|
|
// differs from DOS time and so time() is no good
|
||
|
|
// 05-Jun-1989 SB call DosFindClose if DosFindNext returns an error
|
||
|
|
// 28-May-1989 SB Add getCurDir() to initialize MAKEDIR macro
|
||
|
|
// 24-Apr-1989 SB made FILEINFO a thing of the past. Replace by void *
|
||
|
|
// added OS/2 ver 1.2 support
|
||
|
|
// 05-Apr-1989 SB made all funcs NEAR; Reqd to make all function calls NEAR
|
||
|
|
// 09-Mar-1989 SB Added function QueryFileInfo() because DosFindFirst has FAPI
|
||
|
|
// restrictions. ResultBuf was being allocated on the heap but
|
||
|
|
// not being freed. This saves about 36 bytes for every call to
|
||
|
|
// findAFile i.e. to findFirst(), findNext() or expandWildCards
|
||
|
|
// 09-Nov-1988 SB Created
