Function Documentation

check_vcd()

int check_vcd	(	const std::string &	path,
		void *	buf = nullptr,
		fuse_fill_dir_t	filler = nullptr
	)

Get number of chapters on S/VCD.

Parameters

[in]	path	- Path to check
[in,out]	buf	- The buffer passed to the readdir() operation.
[in,out]	filler	- Function to add an entry in a readdir() operation (see https://libfuse.github.io/doxygen/fuse_8h.html#a7dd132de66a5cc2add2a4eff5d435660)

Note

buf and filler can be nullptr. In that case the call will run faster, so these parameters should only be passed if to be filled in.

Returns

-errno or number of chapters on S/VCD.

create_vcd_virtualfile()

static bool create_vcd_virtualfile ( const VcdEntries &  vcd, const struct stat *  statbuf, void *  buf, fuse_fill_dir_t  filler, bool  full_title, int  chapter_no  )

static

Create a virtual file for a video CD.

Parameters

[in]	vcd	- Video CD handle.
[in]	statbuf	- File status structure of original file.
[in,out]	buf	- The buffer passed to the readdir() operation.
[in,out]	filler	- Function to add an entry in a readdir() operation (see https://libfuse.github.io/doxygen/fuse_8h.html#a7dd132de66a5cc2add2a4eff5d435660)
[in]	full_title	- If true, create virtual file of all title. If false, include single chapter only.
[in]	chapter_no	- Chapter number of virtual file.

Returns

Returns true if successful. Returns false on error.
