16 Finds out the offset (in bytes from the start of the string) of the
17 character at the specified `index' in the string `s'. A zero `index'
18 parameter will return the first character of the string. If `index' is
19 negative, it counts backward from the end of the string, so an `index'
20 of `-1' will return an offset to the last character. Example:
21
22 int from_third_letter = uoffset(text_string, 2);
23
25 Returns the offset in bytes to the specified character.
