help for c-type library

[peterverkaik]

All is??? functions return word, except isalnum which returns byte.
Assuming word is the return type, why do the functions return 0xFF
for true and not 0xFFFF which makes more sense.

Word is used as return type because internal registers and data space memory for dsPIC are organized as 16-bits wide. I am not sure why do mentioned functions return 0xFF for true and not 0xFFFF, however, I informed our developers about this and they will look into it and consider your suggestion. Thank you for the note.
