# Trf\_FlushTransformation(3)

Interface to procedures used to flush buffered characters.

## NAME

Trf\_FlushTransformation - Interface to procedures used to flush buffered characters.

## SYNOPSIS

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

**int Trf\_FlushTransformation**\
 **(**\
\
 	**Trf\_ControlBlock ctrlBlock,**\
\
 	**Tcl\_Interp \*interp,**\
\
 	**ClientData clientData**\
 **);**

## PARAMETERS

- **Trf\_ControlBlock ctrlBlock**

  State of encoder/decoder.

- **Tcl\_Interp \*interp**

  Interpreter for error messages (NULL posssible).

- **ClientData clientData**

  Arbitrary information, as defined in Trf\_TypeDefinition.clientData.

## DESCRIPTION

An encoder/decoder is allowed to buffer characters internally. A procedure of this type is called just before destruction to invoke special processing of such characters. Return value is a standard tcl error code. In case of failure and interp not NULL an error message should be left in the result area of the specified interpreter.
