DBWIN32 is my creation -to solve this problem. - -The code is essentially a merging of a stripped down version of the DBWIN code -from VC 1.5 and DBMON.C with a few 32 bit changes. - -As of version 1.2B, DBWIN32 supports both Win95 and NT. The NT support is -built into the operating system and works just by running DBWIN32. The Win95 -team decided not to support this hook, so I have provided code that will do -this for you. See the file WIN95.TXT for instructions on installing this. - -If you have questions, problems or suggestions about DBWIN32, I welcome your -feedback and plan to actively maintain the code. - -Andrew Tucker -ast@halcyon.com - -To download dbwin32, see e.g.: - -http://ftp.digital.com/pub/micro/NT/WinSite/programr/dbwin32.zip -*/ - -#if !defined(__MWERKS__) && !defined(__SALFORDC__) && !defined(__TWIN32__) -#include -#endif - -void OutputDebugStringW95(const char* lpOutputString, ...) -{ - HANDLE heventDBWIN; /* DBWIN32 synchronization object */ - HANDLE heventData; /* data passing synch object */ - HANDLE hSharedFile; /* memory mapped file shared data */ - LPSTR lpszSharedMem; - char achBuffer[500]; - - /* create the output buffer */ - va_list args; - va_start(args, lpOutputString); - vsprintf(achBuffer, lpOutputString, args); - va_end(args); - - /* - Do a regular OutputDebugString so that the output is - still seen in the debugger window if it exists. - - This ifdef is necessary to avoid infinite recursion - from the inclusion of W95TRACE.H - */ -#ifdef _UNICODE - ::OutputDebugStringW(achBuffer); -#else -#ifdef __TWIN32__ - ::OutputDebugString(achBuffer); -#else - ::OutputDebugStringA(achBuffer); -#endif -#endif - - /* bail if it's not Win95 */ - { - OSVERSIONINFO VerInfo; - VerInfo.dwOSVersionInfoSize = sizeof(OSVERSIONINFO); - GetVersionEx(&VerInfo); - if ( VerInfo.dwPlatformId != VER_PLATFORM_WIN32_WINDOWS ) - return; - } - - /* make sure DBWIN is open and waiting */ - heventDBWIN = OpenEvent(EVENT_MODIFY_STATE, FALSE, "DBWIN_BUFFER_READY"); - if ( !heventDBWIN ) - { - //MessageBox(NULL, "DBWIN_BUFFER_READY nonexistent", NULL, MB_OK); - return; - } - - /* get a handle to the data synch object */ - heventData = OpenEvent(EVENT_MODIFY_STATE, FALSE, "DBWIN_DATA_READY"); - if ( !heventData ) - { - // MessageBox(NULL, "DBWIN_DATA_READY nonexistent", NULL, MB_OK); - CloseHandle(heventDBWIN); - return; - } - - hSharedFile = CreateFileMapping((HANDLE)-1, NULL, PAGE_READWRITE, 0, 4096, "DBWIN_BUFFER"); - if (!hSharedFile) - { - //MessageBox(NULL, "DebugTrace: Unable to create file mapping object DBWIN_BUFFER", "Error", MB_OK); - CloseHandle(heventDBWIN); - CloseHandle(heventData); - return; - } - - lpszSharedMem = (LPSTR)MapViewOfFile(hSharedFile, FILE_MAP_WRITE, 0, 0, 512); - if (!lpszSharedMem) - { - //MessageBox(NULL, "DebugTrace: Unable to map shared memory", "Error", MB_OK); - CloseHandle(heventDBWIN); - CloseHandle(heventData); - return; - } - - /* wait for buffer event */ - WaitForSingleObject(heventDBWIN, INFINITE); - - /* write it to the shared memory */ -#if defined( __BORLANDC__ ) || defined( __MWERKS__ ) || defined(__SALFORDC__) - *((LPDWORD)lpszSharedMem) = getpid(); -#else - *((LPDWORD)lpszSharedMem) = _getpid(); -#endif - - wsprintf(lpszSharedMem + sizeof(DWORD), "%s", achBuffer); - - /* signal data ready event */ - SetEvent(heventData); - - /* clean up handles */ - CloseHandle(hSharedFile); - CloseHandle(heventData); - CloseHandle(heventDBWIN); - - return; -} - - -#endif - - #if 0 // maximum mumber of lines the output console should have
