lgo_UnloadLaygoDll()

Unload the LayGO DLL last loaded by lgo_LoadLaygoDll()

#include "laygodll.h"

LResult  lgo_UnloadLaygoDll
    (
         void
    );

lgo_UnloadLaygoDll() unloads the LayGO DLL loaded by the last successful call to lgo_LoadLaygoDll(). Each successful call to lgo_LoadLaygoDll() must be matched by a call to lgo_UnloadLaygoDll(). Calling any LayGO API function after a successful call to lgo_UnloadLaygoDll() will typically result in abnormal program termination.

As a side-effect, lgo_UnloadLaygoDll() sets the value of the global variable lgo_Fn to NULL.

If successful, lgo_UnloadLaygoDll() returns a non-negative value. Otherwise, it returns a negative value. The return values have no significance other than success and failure.

LaygoDllType dllType = lgo_DLL_LOCAL;

{
    printf("Error: failure loading LayGO DLL.\n");
}

    /* Process... */

    lgo_UnloadLaygoDll();
