|
Abstract:
|
|
|
|
Declares the functions, variables and macros for the progress bar
|
|
utilities. The progress bar utilities manage a single progress bar by
|
|
dividing it into slices. Each slice has an initial static size. The
|
|
count for each slice is scaled independently, so code can dynamically
|
|
change the slice count as an aid to help tick the progress bar more
|
|
smoothly.
