Trf_TransformCharacter

NAME

Trf_TransformCharacter - Interface to procedures for transformation of a single character.

SYNOPSIS

#include <transform.h>

int Trf_TransformCharacter
(

		Trf_ControlBlock ctrlBlock,
		unsigned int character,
		Tcl_Interp *interp,
		ClientData clientData

);

PARAMETERS

Trf_ControlBlock ctrlBlock

State of encoder/decoder.

unsigned int character

Character to transform.

Tcl_Interp *interp

Interpreter for error messages (NULL possible).

ClientData clientData

Arbitrary information, as defined in Trf_TypeDefinition.clientData.

DESCRIPTION

A procedure of this type is called to encode/decode a single character. 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. Only one of ’Trf_TransformCharacter’ and ’Trf_TransformBuffer’ must be provided. This one is easier to implement, the second one should be faster. If both are provided, -> ’Trf_TransformBuffer’ takes precedence.
