Constructor & Destructor Documentation

wibble::sys::Buffer::Buffer

(

)

throw () [inline]

Create a 0-lenght buffer.

wibble::sys::Buffer::Buffer

(

size_t

size

)

[inline]

Create a buffer with the specified size.

References item, and wibble::sys::Buffer::Data::ref().

wibble::sys::Buffer::Buffer	(	void *	buf,
		size_t	size,
		bool	own = true
	)			[inline]

Create a buffer from existing data.

Parameters:

	buf	The data to put in this buffer
	size	The dimension of buf
	own	If true, take ownership of buf, else make a copy of it.

References item, and wibble::sys::Buffer::Data::ref().

wibble::sys::Buffer::Buffer	(	const void *	buf,
		size_t	size
	)			[inline]

Create a buffer with a copy of the given data.

It will always make a copy of the contents of buf.
