# Trf\_ShiftRegister(3)

Shift the register.

## NAME

Trf\_ShiftRegister - Shift the register.

## SYNOPSIS

**#include \<transform.h\>**

**void Trf\_ShiftRegister**\
 **(**\
\
 	**void \*buffer,**\
\
 	**void \*in,**\
\
 	**int shift,**\
\
 	**int buffer\_length**\
 **);**

## PARAMETERS

- **void \*buffer**

  Data shifted to the left.

- **void \*in**

  2nd register shifted into the buffer.

- **int shift**

  Number of bytes to shift out (and in).

- **int buffer\_length**

  Length of buffer and in (in byte).

## DESCRIPTION

The register is shifted 'shift' bytes to the left. The same number of bytes from the left of the 2nd register ('in') is inserted at the right of 'buffer' to replace the lost bytes.
