Re: Unable to output unsigned char/char in hex

[Arthur Schwarz <aschwarz1309 at att dot net>]

Thanks. Is there any way to output a unsigned char/char value without casting it 
to (int) (long ...)?

One reason to do this is to preserve the size of the char. A byte is not defined 
as 8-bits. 8-bits is defined as an octet. I have seen byte sizes of 6, 7, 8, 9, 
12, and 16 bits on various pieces of hardware and whether a wide-char is used. 
Forcing the char to int changes the number of bits used. There are other ways of 
treating the problem(s) but I wonder if there is a way to just output a char in 
hex directly.
