If an argument of a ctype function is outside "unsigned char" and if it is not EOF, the behavior is undefined. The isascii(3) is the sole exception of above and it was used to be used to check a value was valid for other ctype functions in ancient systems. On modern systems, the ctype functions take all values of "unsigned char", and this check is obsolete and even wrong for non-ASCII systems. However, we leave the isascii() untouched for now, so as not to change the current behavior. |
