The len argument must be at least 4 plus the length of suffix, in order to ensure a useful result is generated into buffer. To use a specific prefix, specify this as scale (multiplier = 1024 ^ scale). This cannot be combined with any of the scale flags below.
The following flags may be passed in scale:
HN_AUTOSCALE
Format the buffer using the lowest multiplier possible.
HN_GETSCALE
Return the prefix index number (the number of times number must be divided to fit) instead of formatting it to the buffer.
The following flags may be passed in flags:
HN_DECIMAL
If the final result is less than 10, display it using one digit.
HN_NOSPACE
Do not put a space between number and the prefix.
HN_B
Use ‘B’ (bytes) as prefix if the original result does not have a prefix.
