How to know if is the DLL released?

How about GetModuleHandle()?

hModule = LoadLibrary("somelibrary.dll");
...
FreeLibrary(hModule);
if (GetModuleHandle("somelibrary.dll") != NULL)
// library is still in use

Hi,David Crow
If the A program calls the FreeLibrary(hModule) function,when the B
program is using the DLL.Then,Does the B program produce errors?

No, if both A and B are using the DLL, the reference count will be at least
2. When A frees the DLL, the reference count will be decremented by 1.
Until the reference count reaches 0, Windows will not unload the DLL.

Hi,David Crow
if both A and B are using the DLL,A calls FreeLibrary(hModule),then,A
calls GetModuleHandle("somelibrary.dll") =?
