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.
