label_len
OUT:
Maximum length of the label string
unit_len
OUT:
Maximum length of the unit string
format_len
OUT:
Maximum length of the format string
coords_len
OUT:
Maximum length of the coordinate system string
Purpose
Retrieves the lengths of the label, unit, format, and coordinate system strings.
Return value
Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.
Description
The space allocated for the label, unit, format, and coordinate system strings must be at least one byte larger than the actual length of the string to account for the null termination.
