There's basicly only one place in the code where we start playing a specific song, and that is when you select it on the dir browser. That function makes a playlist of the full dir first. It makes that to proceed with the next song when the selected one ends. > Could I build a playlist for just one file if I wanted to? Certainly. > 2) How are directories and files addressed in the API? For files: open() / close() / read() / write() For dirs: opendir() / readdir() / closedir() > Is it by file/directory name string? Yes. > I see lots of integers seeming to represent directories in the code. Those are file descriptors as returned by one of the function calls above, as in: int fd = open("/myfile.txt", O_RDONLY); if(fd >= 0) { /* we have the file opened, do something */ close(fd); /* close file again */ } else { /* failed to open the file */ } -- Daniel Stenberg -- http://rockbox.haxx.se/ -- http://daniel.haxx.se/Received on 2003-05-02 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
