According the standard, char is supposed to be a distinct type from signed/unsigned char. btw, most commonly-used compilers (gcc, msvc, etc.) does use these defaults, but you can't even assume that for every compilers. If one wants to check the signedness of char, she could check CHAR_MIN is equal to zero or SCHAR_MIN (from limits.h) Regards, H. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
