/*****************************************************************************\ * MODULE: webpnp.cxx * * This module contains routines which read/write printer-configuration * data to a BIN-File. The file format is depicted below. The file begins * with a header indicating the number of (pData) items. THIS DOES NOT * include the DEVMODEW in its item-count. So, at a minimum, this code * could result in the setting of a DEVMODE, or just setting the printer * data, depending upon the header information. * * * DEVBIN_HEAD DEVBIN_INFO ...-> DEVBIN_INFO * -------------------------------------------------------------------------- * | | cbSize | cbSize | * | bDevMode |------------------------------|------------------------------| * | cItems | | | | cbData | | | | cbData | * | | Type | Key | Name |----------| Type | Key | Name |----------| * | | | | | DevModeW | | | | pData 0 | * -------------------------------------------------------------------------- * * The usage scenario is for webWritePrinterInfo() to query a printer and * write out the DEVMODEW and Printer-Configuration data to this file-format. * On a call to webReadPrinterInfo(), a particular printer is opened, and * the BIN-File is read. The printer is then reset to the information * contained in the BIN-File. This is accomplished by doing a GetPrinter(2) * on the opened-printer, then re-configuring the PRINT_INFO_2 information * and reseting the the printer through SetPrinter(2). * * Likewise, if there exists printer-data, the information is set to the * opened printer through SetPrinterData() calls. * * * NOTE: The DEVMODE is always the FIRST entry in this file following the * DEVBIN_HEAD. * * NOTE: The (cItems) only refers to the (Printer-Data) fields. It does * not count the DEVMODEW. * * NOTE: The processing for ICM-Profile enumeration is performed in unicode * strings and only converted to TCHAR type strings on callbacks to * the caller of the enum API. This is desirable to maintain a level * of consistency when dealing with text. * * * Copyright (C) 1996-1997 Microsoft Corporation * Copyright (C) 1996-1997 Hewlett Packard * * history: * 25-Feb-1997 created. * \*****************************************************************************/ #include "spllibp.hxx" #include #include #include #include /***************************************\ * Static Strings. \***************************************/ static CONST WCHAR s_wszCopyFiles[] = L"CopyFiles"; static CONST WCHAR s_wszDir[] = L"Directory"; static CONST WCHAR s_wszFil[] = L"Files"; static CONST WCHAR s_wszMod[] = L"Module"; static CONST CHAR s_szGCFP[] = "GenerateCopyFilePaths"; /*****************************************************************************\ * web_GAlloc (Local Routine) * * Allocates a block of memory. * \*****************************************************************************/ inline LPVOID web_GAlloc( DWORD cbSize) { return new BYTE[cbSize]; } /*****************************************************************************\ * web_GFree (Local Routine) * * Deletes the memory-block allocated via web_GAlloc(). * \*****************************************************************************/ inline BOOL web_GFree( LPVOID lpMem) { delete [] lpMem; return TRUE; } /*****************************************************************************\ * web_AlignSize (Local Routine) * * Returns size (bytes) of the memory-block.
