al_ustr_replace_range (3alleg5)

• #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_pos, end_pos) with the contents of us2. start_pos cannot be less than 0. If start_pos is past the end of us1 then the space between the end of the string and start_pos will be padded with NUL (\[aq]\[aq]) bytes.

Use al_ustr_offset(3alleg5) to find the byte offsets.

Returns true on success, false on error.
