isascii & isextendedascii implementation

I know that there exists a function that says whether a particular character is ascii or not (i.e, isascii), is there any similar function that can say whether a character is an extended ascii. If possible can i have the internal implementaation of both.

Thanks in advance.

The google search for isextendedascii turned up only three links. All of them seem to be for java... check it out

Define 'extended ascii'. Do you mean multibyte characters in UTF8 or something like that?

The definition of isascii is simple:
// Valid ASCII characters are 0-127
int isascii(int char)
  return((char <= 127) && (char >= 0));
