Detailed Description

CharInputBuffer.hpp provides an InputBuffer for plain character arrays (buffers).

Constructor & Destructor Documentation

CharInputBuffer::CharInputBuffer	(	unsigned char *	buf,
		size_t	size,
		bool	owner = false
	)			[inline]

Construct a CharInputBuffer.hpp object with a char* buffer of 'size' if 'owner' is true, then the buffer will be delete[]-ed on destruction.

Note:

it is assumed the buffer was allocated with new[]!

Destructor

Note:

If you're using malloced data, then you probably need to change this destructor. Or better use this class as template for your own.
