34: FUNCTION: LibMain(HANDLE, WORD, WORD, LPSTR)
35:
36: PURPOSE: Is called by LibEntry. LibEntry is called by Windows when
37: the DLL is loaded. The LibEntry routine is provided in
38: the LIBENTRY.OBJ in the SDK Link Libraries disk. (The
39: source LIBENTRY.ASM is also provided.)
40:
41: LibEntry initializes the DLL's heap, if a HEAPSIZE value is
42: specified in the DLL's DEF file. Then LibEntry calls
43: LibMain. The LibMain function below satisfies that call.
44:
45: The LibMain function should perform additional initialization
46: tasks required by the DLL. In this example, no initialization
47: tasks are required. LibMain should return a value of 1 if
48: the initialization is successful.
