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.
