*dllmain.c - Dummy DllMain for user DLLs that have no notification handler
|

|

|
||
|
|
* Copyright (c) 1993-2001, Microsoft Corporation. All rights reserved.
|
||
|
|
*
|
||
|
|
*Purpose:
|
||
|
|
* This object goes into LIBC.LIB and LIBCMT.LIB and MSVCRT.LIB for use
|
||
|
|
* when linking a DLL with one of the three models of C run-time library.
|
||
|
|
* If the user does not provide a DllMain notification routine, this
|
||
|
|
* dummy handler will be linked in. It always returns TRUE (success).
|
||
|
|
*
|
||
|
|
*Revision History:
|
||
|
|
* 04-14-93 SKS Initial version
|
||
|
|
* 02-22-95 JCF Spliced _WIN32 & Mac versions.
|
||
|
|
* 04-06-95 SKS In LIBC.LIB and MSVCRT.LIB models, turn off thread
|
||
|
|
* attach and detach notifications to the current DLL.
|
||
|
|
* 05-17-99 PML Remove all Macintosh support.

*DllMain - dummy version DLLs linked with all 3 C Run-Time Library models
|
||
|
|
*
|
||
|
|
*Purpose:
|
||
|
|
* The routine DllMain is always called by _DllMainCrtStartup. If
|
||
|
|
* the user does not provide a routine named DllMain, this one will
|
||
|
|
* get linked in so that _DllMainCRTStartup has something to call.
|
||
|
|
*
|
||
|
|
* For the LIBC.LIB and MSVCRT.LIB models, the CRTL does not need
|
||
|
|
* per-thread notifications so if the user is ignoring them (default
|
||
|
|
* DllMain and _pRawDllMain == NULL), just turn them off. (WIN32-only)
