uoffset - Man Page

#include <allegro.h>

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

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);

Returns the offset in bytes to the specified character.
