Detailed Description

The advgetopt allows for validating the input parameters automatically. This one validator checks whether the input represents what is considered a valid size of bits or bytes.

This includes a floating point number followed by a suffix such as "kB" or "Gb" or "TiB".

Note

The size can also represents bits, even though it was written to read bytes. If your command line option is expecting a size in bits, this works just as expected.

The size conversions are based on the International System of Units (SI).
