--- Comment #39 from Qing Zhao <qing.zhao at oracle dot com> --- > --- Comment #38 from Wilco <wilco at gcc dot gnu.org> --- > This uses signed char while the C standard says the comparison is done on > unsigned chars. > during my implementation, I did some research on whether I should use “unsigned char” or “signed char” for the comparison. what I checked was man page of strcmp, memcmp, (I don’t have C standard in hand). in the manpage of memcmp, it clearly and explicitly mentioned that the chars are interpreted as unsigned char; however, in the manpage of strcmp/strncmp, it’s not mentioned at all. So, I thought that for strcmp/strncmp, I should use signed char. but for memcmp, I used unsigned char. since I don’t have a C standard, could you please point me the corresponding section for this? thanks.
