#include <allegro5/allegro.h>

bool al_ustr_replace_range(ALLEGRO_USTR *us1, int start_pos1, int end_pos1,
   const ALLEGRO_USTR *us2)

Replace the part of us1 in the byte interval [start_pos1, end_pos1) with the contents of us2. start_pos1 cannot be less than 0. If start_pos1 is past the end of us1 then the space between the end of the string and start_pos1 will be padded with NUL ('\0') bytes.

Use al_ustr_offset(3) to find the byte offsets.

Returns true on success, false on error.
