// DESCRIPTION
|
||
|
|
//
|
||
|
|
// This function has two important things to do. It gets called
|
||
|
|
// at a few different points in the process of reading or writing data
|
||
|
|
// from storage objects. During normal reading and writing, it
|
||
|
|
// will get called every time the buffer is loaded or flushed.
|
||
|
|
//
|
||
|
|
// If we are in Windows mode, we execute a PeekMessage() loop. This
|
||
|
|
// makes sure that we aren't hogging the CPU. By doing it this way,
|
||
|
|
// the programmer can be ensure that he/she is being a good citizen
|
||
|
|
// without any significant effort.
|
||
|
|
//
|
||
|
|
// The second important function is that of calling the monitor function.
|
||
|
|
// The user interface elements need to be updated regularly, and this
|
||
|
|
// is done via this call.
