c++ - libspotify: Access violation reading location 0x00000000. (Windows) -


so, try specific playlist via uri this:

sp_link *link; sp_playlist *playlist; sp_playlist_callbacks playlist_callbacks = { 0 };  link = sp_link_create_from_string("spotify:user:spotify:playlist:2iy4blinjmogjx4qhcwnju"); playlist_callbacks.playlist_state_changed = playlist_state_changed;  waitforsingleobject(lib_lock, infinite); playlist = sp_playlist_create(session, link);              // <- program crashes here sp_playlist_add_callbacks(playlist, &playlist_callbacks, null); waitforsingleobject(lib_event_call_finished, infinite); releasemutex(lib_lock);

the callback following:

void sp_callconv playlist_state_changed(sp_playlist *playlist, void *user_data) {     if (sp_playlist_is_loaded(playlist)) {         setevent(lib_event_call_finished);     } }

lib_lock mutex (createmutex(null, false, null);)

lib_event_call_finshed event (createevent(null, false, false, null);)

one word program's architecture:

i have thread executing above commands, created in main function. main function executes main loop:

while (true) {     result = waitforsingleobject(lib_event_notify, next_timeout);     if (result == wait_object_0 || result == wait_timeout) {         {             sp_session_process_events(session, &next_timeout);         } while (next_timeout == 0);     } else {         err_msg("waitforsingleobject has failed");     } }

lib_event_notify event, called when notify_main_thread called.

when marked line executed following error visual studio:

unhandled exception @ 0x100a5550 (libspotify.dll) in prog.exe: 0xc0000005: access violation reading location 0x00000000.
