NAME

       Trf_TransformBuffer - Interface to procedures for transformation of character sequences.

SYNOPSIS

       #include <transform.h>

       int Trf_TransformBuffer
       (
            Trf_ControlBlock ctrlBlock,
            unsigned char *buf,
            int bufLen,
            Tcl_Interp *interp,
            ClientData clientData
       );

PARAMETERS

       Trf_ControlBlock ctrlBlock
              State of encoder/decoder.

       unsigned char *buf
              Characters to transform.

       int bufLen
              Number of characters.

       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 complete buffer. 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. The first named is easier to implement, this one should be faster. If  both  are  provided,  ->
       'Trf_TransformBuffer' takes precedence.
