◆ copy()

long long MythFile::copy	(	QFile &	dst,
		QFile &	src,
		uint	block_size = `0`
	)

Copies src file to dst file.

If the dst file is open, it must be open for writing. If the src file is open, if must be open for reading.

The files will be in the same open or close state after this function runs as they were prior to this function being called.

This function does not care if the files are actual files. For compatibility with pipes and socket streams the file location will not be reset to 0 at the end of this function. If the function is successful the file pointers will be at the end of the copied data.

Parameters

dst	Destination QFile
src	Source QFile
block_size	Optional block size in bytes, must be at least 1024, otherwise the default of 16 KB will be used.

Returns: bytes copied on success, -1 on failure.
