Member Function Documentation

open()

FXbool FX::FXMemoryStream::open	(	FXStreamDirection	save_or_load,
		FXuchar *	data = nullptr,
		FXuval	size = ~0UL,
		FXbool	owned = false
	)

Open memory stream.

When reading from the data buffer, the size parameter is optional. If not given, the reader will need to know when to stop reading by some other means, like end-of-file markers in the data. When writing, the size parameter must be set to reflect the actual buffer size, and should be at least 16. If the owned flag is true, the stream becomes the owner of the data buffer; otherwise, the stream will not delete the buffer. Passing NULL for the data buffer will cause the stream to allocate a buffer of the given size.
