       This function is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.10                                     SDL_wcsnstr(3)

       The  search  ends once it finds the requested substring, or a null terminator value to end the string, or
       maxlen wide character have been examined. It is possible to use this function on a wide string without  a
       null terminator.

       Note  that  this  looks  for  strings of _wide characters_, not _codepoints_, so it's legal to search for
       malformed and incomplete UTF-16 sequences.
