Trf_TransformCharacter3
Interface to procedures for transformation of a single character.
Usage
#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. |
Overview
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.
