Detailed Description

Byte buffer provides functionality for reading/writing arbitrary data from/to a chunk of memory.

Every function is guarded with bounds checking to prevent accidental out of bounds access. Read buffer differs from write buffer in that the memory for it is write-protected (const). Bounds checking is done with assertions.

Macro Definition Documentation

#define kzcByteBufferRead	(	buffer_param,
		value_param
	)

Read arbitrary type from the given buffer.

The size of the type is taken automatically.

#define kzcByteBufferBackwardsRead	(	buffer_param,
		value_param
	)

Read arbitrary type from the given backwards buffer.

The size of the type is taken automatically.

#define kzcByteBufferWrite	(	buffer_param,
		value_param
	)

Write arbitrary type to the given buffer.

The size of the type is taken automatically.

#define kzcByteBufferBackwardsWrite	(	buffer_param,
		value_param
	)

Write arbitrary type to the given backwards buffer.

The size of the type is taken automatically.

#define kzcByteBufferReset ( buffer_param )

Reset the buffer offset back to zero.

#define kzcByteBufferSkip	(	buffer_param,
		offset_param
	)

Skip given amount of bytes in the buffer.

#define kzcByteBufferGetOffset ( buffer_param )

Get the current offset in the buffer.

#define kzcByteBufferSetOffset	(	buffer_param,
		offset_param
	)

Set the current offset in the buffer.

#define kzcByteBufferIsFinished ( buffer_param )

Check if the buffer has been read or written completely.
