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.
