Generic routines are normally written to accept uint8_t or uin16_t arguments. This covers the widest range of cases.
Then if you want to use a 'special' case, you cast your 'special' signed argument to the type of argument specified by the function prototype. Your textbooks will explain the rules for sign-extension etc for casting up or down. Compilers are becoming more pedantic about your use of types. So most <string.h> functions are going to specify that you use 'char' rather than 'signed char' or 'unsigned char'. It is VERY important that you understand when and where you should cast 'specials' or use the most appropriate type in the first place. David. |
