sf2::Sample::buffer_t Struct Reference

Pointer address and size of a buffer. More...

#include <SF.h>

List of all members.

Public Member Functions
	buffer_t ()
Public Attributes
void *	pStart
	Points to the beginning of the buffer.
unsigned long	Size
	Size of the actual data in the buffer in bytes.
unsigned long	NullExtensionSize
	The buffer might be bigger than the actual data, if that's the case that unused space at the end of the buffer is filled with NULLs and NullExtensionSize reflects that unused buffer space in bytes. Those NULL extensions are mandatory for differential algorithms that have to take the following data words into account, thus have to access past the buffer's boundary. If you don't know what I'm talking about, just forget this variable. :).
