Generic Bit-Buffer Structure and Function Library (bitbuf.c)

Detailed Description

 #include "bitbuf.h" 

Overview

This bit-buffer structure provides an easy and efficient way to store and process bits. You can create as many bit buffers as you like (within memory limits), and then use this common set of functions to access each buffer. Supported functions include sequential getting and storing of bits, array-like get, buffer flush (dump data), and reset-to-beginning. This buffer is not dynamically allocated, it has a user-defined fixed maximum size.

Data Structures
struct	struct_BitBuf
Typedefs
typedef struct_BitBuf	BitBuf
Functions
void	bitbufInit (BitBuf *bitBuffer, unsigned char *start, unsigned short bytesize)
	initialize a buffer to start at a given address and have given size
unsigned char	bitbufGet (BitBuf *bitBuffer)
	get the bit at the current position in the buffer
unsigned char	bitbufGetAtIndex (BitBuf *bitBuffer, unsigned short bitIndex)
	get a bit at the specified index in the buffer (kind of like array access)
void	bitbufStore (BitBuf *bitBuffer, unsigned char bit)
	store a bit at the current position in the buffer
unsigned short	bitbufGetDataLength (BitBuf *bitBuffer)
	return the number of bits in the buffer
void	bitbufReset (BitBuf *bitBuffer)
	resets the read/write position of the buffer to beginning
void	bitbufFlush (BitBuf *bitBuffer)
	flush (clear) the contents of the buffer
