// Implementation note:
//
// The Implementation for OS/2 and Win32 are nearly the same. Most of the
// functions are implemented exactly the same way. The only difference is
// the signal handling. The OS/2 implementation needs a event semaphore
// which will be posted if an event occures. The Win32 implementation
// only provides a function CAPI_WAIT_FOR_EVENT; the function returns,
// if an event occures.
// The internal structure ImplCapi gives us the room for the event semaphore
// handle. The event semaphore will be created the first time,
// CAPI_WAIT_FOR_EVENT is called since some applications don't need this
// functionality (actually they poll the CAPI)
