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.
