The following table contains values that can be set with class VFSUrl :

Name	Type	Get call
URL	`std::string`	GetURL
Domain name	`std::string`	GetDomain
Hostname	`std::string`	GetHostname
Filename	`std::string`	GetFilename
Network port	`unsigned int`	GetPort
Special options	`std::string`	GetOptions
Username	`std::string`	GetUsername
Password	`std::string`	GetPassword
Get URL with user and password hidden	`std::string`	GetRedacted
Sharename	`std::string`	GetSharename
Network protocol	`std::string`	GetProtocol

◆ OpenForWrite()

virtual kodi::addon::VFSFileHandle OpenForWrite	(	const kodi::addon::VFSUrl &	url,
		bool	overWrite
	)

inlinevirtual

Open a file for output.

Parameters

[in]	url	The URL of the file
[in]	overWrite	Whether or not to overwrite an existing file

Returns: Context for the opened file

◆ Close()

virtual bool Close ( kodi::addon::VFSFileHandle context )

inlinevirtual

Close a file.

Parameters

[in] context The context of the file

Returns: True on success, false on failure

◆ Read()

virtual ssize_t Read	(	kodi::addon::VFSFileHandle	context,
		uint8_t *	buffer,
		size_t	uiBufSize
	)

inlinevirtual

Read from a file.

Parameters

[in]	context	The context of the file
[out]	buffer	The buffer to read data into
[in]	uiBufSize	Number of bytes to read

Returns: Number of bytes read

◆ Write()

virtual ssize_t Write	(	kodi::addon::VFSFileHandle	context,
		const uint8_t *	buffer,
		size_t	uiBufSize
	)

inlinevirtual

Write to a file.

Parameters

[in]	context	The context of the file
[in]	buffer	The buffer to read data from
[in]	uiBufSize	Number of bytes to write

Returns: Number of bytes written

◆ Seek()

virtual int64_t Seek	(	kodi::addon::VFSFileHandle	context,
		int64_t	position,
		int	whence
	)

inlinevirtual

Seek in a file.

Parameters

[in] context The context of the file

[in] position The position to seek to

[in]

whence

Position in file 'position' is relative to (SEEK_CUR, SEEK_SET, SEEK_END):

Value	int	Description
SEEK_SET	0	position is relative to the beginning of the file. This is probably what you had in mind anyway, and is the most commonly used value for whence.
SEEK_CUR	1	position is relative to the current file pointer position. So, in effect, you can say, "Move to my current position plus 30 bytes," or, "move to my current position minus 20 bytes."
SEEK_END	2	position is relative to the end of the file. Just like SEEK_SET except from the other end of the file. Be sure to use negative values for offset if you want to back up from the end of the file, instead of going past the end into oblivion.

Returns: Offset in file after seek

◆ Truncate()

virtual int Truncate	(	kodi::addon::VFSFileHandle	context,
		int64_t	size
	)

inlinevirtual

Truncate a file.

Parameters

[in]	context	The context of the file
[in]	size	The size to truncate the file to

Returns: 0 on success, -1 on error

◆ GetLength()

virtual int64_t GetLength ( kodi::addon::VFSFileHandle context )

inlinevirtual

Get total size of a file.

Parameters

[in] context The context of the file

Returns: Total file size

◆ GetPosition()

virtual int64_t GetPosition ( kodi::addon::VFSFileHandle context )

inlinevirtual

Get current position in a file.

Parameters

[in] context The context of the file

Returns: Current position

◆ GetChunkSize()

virtual int GetChunkSize ( kodi::addon::VFSFileHandle context )

inlinevirtual

Get chunk size of a file.

Parameters

[in] context The context of the file
