inline

◆ fstream() [2/2]

fstream::fstream	(	const char *	path,
		openmode	mode = `in \| out`
	)

inlineexplicit

Constructor with open

Parameters

[in]	path	file to open
[in]	mode	open mode

◆ ~fstream()

fstream::~fstream ( )

inline

Member Function Documentation

◆ clear()

void fstream::clear ( iostate state = goodbit )

inline

Clear state and writeError

Parameters

[in] state new state for stream

◆ close()

void fstream::close ( )

inline

Close a file and force cached data and directory information to be written to the storage device.

◆ is_open()

bool fstream::is_open ( )

inline

Returns: True if stream is open else false.

◆ open()

void fstream::open	(	const char *	path,
		openmode	mode = `in \| out`
	)

inline

Open a fstream

Parameters

[in]	path	path to open
[in]	mode	open mode

Valid open modes are (at end, ios::ate, and/or ios::binary may be added):

ios::in - Open file for reading.

ios::out or ios::out | ios::trunc - Truncate to 0 length, if existent, or create a file for writing only.

ios::app or ios::out | ios::app - Append; open or create file for writing at end-of-file.

ios::in | ios::out - Open file for update (reading and writing).

ios::in | ios::out | ios::trunc - Truncate to zero length, if existent, or create file for update.

ios::in | ios::app or ios::in | ios::out | ios::app - Append; open or create text file for update, writing at end of file.
