[lwip-devel] [bug #52611] Incorrect use of ctype macros?

[Mike Kleshov]

Update of bug #52611 (project lwip):

             Open/Closed:                  Closed => Open

Follow-up Comment #3:

The reference you are referring to also says "The c argument is an int, the
value of which the application shall ensure is a character representable as an
unsigned char or equal to the value of the macro EOF".
I can easily see how an argument to those macros could have a value of -2, for
example, which is a no-no.
