// FUNCTION: DLLMain(HINSTANCE, DWORD, LPVOID)
|
||
|
|
|
||
|
|
// PURPOSE: Called when DLL is loaded by a process, and when new
|
||
|
|
// threads are created by a process that has already loaded the
|
||
|
|
// DLL. Also called when threads of a process that has loaded the
|
||
|
|
// DLL exit cleanly and when the process itself unloads the DLL.
|
||
|
|
|
||
|
|
// PARAMETERS:
|
||
|
|
// hDLLInst - Instance handle of the DLL
|
||
|
|
// fdwReason - Process attach/detach or thread attach/detach
|
||
|
|
// lpvReserved - Reserved and not used
|
||
|
|
|
||
|
|
// RETURN VALUE: (Used only when fdwReason == DLL_PROCESS_ATTACH)
|
||
|
|
// TRUE - Used to signify that the DLL should remain loaded.
|
||
|
|
// FALSE - Used to signify that the DLL should be immediately unloaded.
|
||
|
|
|
||
|
|
// COMMENTS:
|
||
|
|
|
||
|
|
// If you want to use C runtime libraries, keep this function named
|
||
|
|
// "DllMain" and you won't have to do anything special to initialize
|
||
|
|
// the runtime libraries.
|
||
|
|
|
||
|
|
// When fdwReason == DLL_PROCESS_ATTACH, the return value is used to
|
||
|
|
// determine if the DLL should remain loaded, or should be immediately
|
||
|
|
// unloaded depending upon whether the DLL could be initialized properly.
|
||
|
|
// For all other values of fdwReason, the return value is ignored.
