dll - 暂停 DLL 导出，直到被 EXE 触发

Answer 1

You can use CreateEvent, SetEvent, and WaitForSingleObject. If the dll was loaded by the executable that needs to signal the event that is all that is required. If it is from separate executables it is only slightly more complicated. When you call CreateEvent, create a named Event. This named event can be accessed by multiple processes. If it needs to work across different users logged in, prefix the name with "Global\" and it will be the same event for all processes for all users.

//in dll
HANDLE eventHandle = CreateEvent( NULL, TRUE, FALSE, "Global\\My-Unique-Trigger-Event" );
//do stuff
WaitForSingleObject( eventHandle, INFINITE);
//exit

//in executable
HANDLE eventHandle = CreateEvent( NULL, TRUE, FALSE, "Global\\My-Unique-Trigger-Event" );
SetEvent( eventHandle );
