NAME
Trf_CreateCtrlBlock - Interface to procedure for creation of
encoder/decoder control structures.
SYNOPSIS
#include <transform.h>
Trf_ControlBlock Trf_CreateCtrlBlock
(
ClientData writeClientData,
Trf_WriteProc *fun,
Trf_Options optInfo,
Tcl_Interp *interp,
ClientData clientData
);
PARAMETERS
ClientData writeClientData
Arbitrary information given as clientdata to ’fun’.
Trf_WriteProc *fun
Vector to use for writing generated results.
Trf_Options optInfo
Options to configure the control.
Tcl_Interp *interp
Interpreter for error messages.
ClientData clientData
Arbitrary information, as defined in
Trf_TypeDefinition.clientData.
