Detailed Description

Represents a random-access file, usually stored on a disk. Files are always binary: that is, they do no end-of-line transformations. File objects are roughly analogous to ANSI C FILE* objects.

Member Enumeration Documentation

enum corona::File::SeekMode

The different ways you can seek within a file.

Enumerator:

BEGIN	relative to the beginning of the file
CURRENT	relative to the current position in the file
END	relative to the end of the file: position should be negative

Member Function Documentation

virtual int COR_CALL corona::File::read	(	void *	buffer,
		int	size
	)			[pure virtual]

Read size bytes from the file, storing them in buffer.

Parameters:

	buffer	buffer to read into
	size	number of bytes to read

Returns:

number of bytes successfully read

virtual int COR_CALL corona::File::write	(	const void *	buffer,
		int	size
	)			[pure virtual]

Write size bytes from buffer to the file.

Parameters:

	buffer	buffer that contains the data to write
	size	number of bytes to write

Returns:

number of bytes successfully written

virtual bool COR_CALL corona::File::seek	(	int	position,
		SeekMode	mode
	)			[pure virtual]

Jump to a new position in the file, using the specified seek mode. Remember: if mode is END, the position must be negative, to seek backwards from the end of the file into its contents. If the seek fails, the current position is undefined.

Parameters:

	position	position relative to the mode
	mode	where to seek from in the file

Returns:

true on success, false otherwise

virtual int COR_CALL corona::File::tell

(

)

[pure virtual]

Get current position within the file.

Returns:

current position
