CoLoadLibrary

Loads a specific DLL into the caller's process. The CoGetClassObject function calls CoLoadLibrary internally; applications should not call it directly.

HINSTANCE CoLoadLibrary(
  LPOLESTR lpszLibName,
                  //Pointer to the name of the library to be loaded
  BOOL bAutoFree  //Whether library is automatically freed
);
 

Parameters

lpszLibName

[in] Pointer to the name of the library to be loaded. The use of this name is the same as in the Win32 function LoadLibrary.

bAutoFree

[in] If TRUE, indicates that this library is freed when it is no longer needed, through a call to either the CoFreeUnusedLibraries or CoUninitialize functions. If FALSE, the library should be explicitly freed with the CoFreeLibrary function.

Return Values

Module Handle

Handle of the loaded library.

NULL

Library could not be loaded.

Remarks

The CoLoadLibrary function is called internally by the CoGetClassObject function when the class context (CLSCTX) indicates a DLL. CoLoadLibrary loads a DLL specified by the lpszLibName parameter into the process that called CoGetClassObject. Containers should not call CoLoadLibrary directly.

Internally, a reference count is kept on the loaded DLL, by using CoLoadLibrary to increment the count and the CoFreeLibrary function to decrement it.

Windows CE: Passing into this function any invalid and, under some circumstances, NULL pointers will result in unexpected termination of the application. For more information about handling exceptions, see Programming Considerations.
