al_android_open_fd - Allegro 5 API

       Opens  a  file  descriptor  to  access  data  under a Universal Resource Identifier (URI).  This function
       accepts content:// and  file://  URI  schemes.   You  are  responsible  for  closing  the  returned  file
       descriptor.

       The file mode can be "r", "w", "rw", "wt", "wa" or "rwt".  The exact implementation of these modes differ
       depending on the underlying content provider.  For example, "w" may or may not truncate.

       Returns  a file descriptor on success or a negative value on an error.  On an error, the Allegro errno is
       set.

              Note: Remember to add to your manifest file the relevant permissions to your app.

       Example:

              const char *content_uri = "content://...";
              int fd = al_android_open_fd(content_uri, "r");

              if (fd >= 0) {
                  ALLEGRO_FILE *f = al_fopen_fd(fd, "r");

                  if (f != NULL) {
                      do_something_with(f);
                      al_fclose(f);
                  }
                  else {
                      handle_error(al_get_errno());
                      close(fd);
                  }
              }
              else {
                  handle_error(al_get_errno());
              }
