SYNOPSIS

#include <transform.h>

int Trf_WriteProc
(
       ClientData clientData,

       unsigned char *outString,

       int outLen,

       Tcl_Interp *interp

);

PARAMETERS

ClientData clientData

Arbitrary information, defined during controlblock creation.

unsigned char *outString

Buffer with characters to write.

int outLen

Number of characters in buffer.

Tcl_Interp *interp

Interpreter for error messages (NULL possible).

DESCRIPTION

Procedures of this type are called by an encoder/decoder to write (partial) transformation results, decoupling the final destination from result generation. 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.
