Use Unsigned Chars

The C compiler can automatically treat a char declarations as unsigned char. This behavior is controlled by the Use Unsigned Chars setting in the C/C++ Language Panel.

When the Use Unsigned Chars option is on, the C compiler treats a char declaration as if it were an unsigned char declaration.


NOTE

If you turn this option on, your code may not be compatible with libraries that were compiled with this option turned off.

The Use Unsigned Chars option corresponds to the pragma unsigned_char. To check whether this option is on, use __option (unsigned_char). By default, this option is off.

See also "unsigned_char" and "Checking Options."
