Trf_SetObjOption(3) Interface to procedures to define the value of an option.

SYNOPSIS

#include <transform.h>

int Trf_SetObjOption
(
       Trf_Options options,

       Tcl_Interp *interp,

       const char *optname,

       const Tcl_Obj *optvalue,

       ClientData clientData

);

PARAMETERS

Trf_Options options
Container to place the value into.
Tcl_Interp *interp
Interpreter for error messages (NULL possible).
const char *optname
Name of option to define.
const Tcl_Obj *optvalue
Value to set into the container.
ClientData clientData
Arbitrary information, as defined in Trf_TypeDefinition.clientData.

DESCRIPTION

The procedure takes the specified optionname (rejecting illegal ones) and places the given optionvalue into the container. All necessary conversions from a Tcl_Obj to the required type should be done here. 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. This procedure makes sense for tcl version 8 and above only.
