uinsert

#include <allegro.h>

int uinsert(char *s, int index, int c);

Inserts the character `c' at the specified `index' in the string, sliding the rest of the data along to make room. If `index' is negative, it counts backward from the end of the string. Example:

   uinsert(text_string, 0, prefix_letter);

Returns the number of bytes by which the trailing part of the string was moved.
