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.
