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.

DESCRIPTION

       The  procedure  has  to	create	a control structure for an encoder/decoder. The structure must be initialized with the contents of the the
       option container. Return value is an opaque handle aof the control structure or NULL in case of failure. An error message should be left in
       the result area of the specified interpreter then.
