Trf_CreateCtrlBlock(3)					     Library Functions Manual					    Trf_CreateCtrlBlock(3)

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.

NAME

       Tcl_CallWhenDeleted, Tcl_DontCallWhenDeleted - Arrange for callback when interpreter is deleted

SYNOPSIS

       #include <tcl.h>

       Tcl_CallWhenDeleted(interp, proc, clientData)

       Tcl_DontCallWhenDeleted(interp, proc, clientData)

ARGUMENTS

       Tcl_Interp *interp (in)			     Interpreter with which to associated callback.

       Tcl_InterpDeleteProc *proc (in)		     Procedure to call when interp is deleted.

       ClientData clientData (in)		     Arbitrary one-word value to pass to proc.
_________________________________________________________________

DESCRIPTION

       Tcl_CallWhenDeleted arranges for proc to be called by Tcl_DeleteInterp if/when interp is deleted at some future time.  Proc will be invoked
       just before the interpreter is deleted, but the interpreter will still be valid at the time of the call.  Proc should  have  arguments  and
       result that match the type Tcl_InterpDeleteProc:
	      typedef void Tcl_InterpDeleteProc(
		      ClientData clientData,
		      Tcl_Interp *interp);
       The clientData and interp parameters are copies of the clientData and interp arguments given to Tcl_CallWhenDeleted.  Typically, clientData
       points to an application-specific data structure that proc uses to perform cleanup when an interpreter is about to go away.  Proc does  not
       return a value.

       Tcl_DontCallWhenDeleted	cancels  a previous call to Tcl_CallWhenDeleted with the same arguments, so that proc will not be called after all
       when interp is deleted.	If there is no deletion callback that matches interp, proc, and clientData  then  the  call  to  Tcl_DontCallWhen-
       Deleted has no effect.
