uoffset(3)                      Allegro manual                      uoffset(3)

NAME
       uoffset - Finds the offset of a character in a string. Allegro game
       programming library.

SYNOPSIS
       #include <allegro.h>

       int uoffset(const char *s, int index);

DESCRIPTION
       Finds out the offset (in bytes from the start of the string) of the
       character at the specified `index' in the string `s'. A zero `index'
       parameter will return the first character of the string. If `index' is
       negative, it counts backward from the end of the string, so an `index'
       of `-1' will return an offset to the last character. Example:

          int from_third_letter = uoffset(text_string, 2);

RETURN VALUE
       Returns the offset in bytes to the specified character.
