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.
