Typedef Documentation

typedef bool(* media_bookmark_cb)(media_bookmark_h bookmark, void *user_data)

Called for every bookmark in the obtained list of bookmarks.

Iterates over a bookmark list.

Since :: 2.3

Remarks:: To use the bookmark outside this function, copy the handle with the media_bookmark_clone() function.
The callback is called in the main loop.

Parameters:

[in]	bookmark	The handle to the media bookmark
[in]	user_data	The user data passed from the foreach function

Returns:: true to continue with the next iteration of the loop, otherwise false to break out of the loop

Precondition:: media_info_foreach_bookmark_from_db() will invoke this function.

To use this handle outside of these foreach functions, use this function.
