Definiciones de estructura y de constante

La rutina auxiliar predeterminada utiliza varias estructuras para comunicarse con las funciones de enlace durante las excepciones.Estos son los valores de notificación y de error, las estructuras de información y el tipo de puntero a función de enlace que se pasa a los enlaces:

//
// Delay load import hook notifications
//
enum {
    dliStartProcessing,        // used to bypass or note helper only
    dliNotePreLoadLibrary,     // called just before LoadLibrary, can
                               //  override w/ new HMODULE return val
    dliNotePreGetProcAddress,  // called just before GetProcAddress, can
                               //  override w/ new FARPROC return value
    dliFailLoadLib,            // failed to load library, fix it by
                               //  returning a valid HMODULE
    dliFailGetProc,            // failed to get proc address, fix it by
                               //  returning a valid FARPROC
    dliNoteEndProcessing,      // called after all processing is done, no
                               //  bypass possible at this point except
                               //  by longjmp()/throw()/RaiseException.
