Simpler Tcl way for extracting method variables

[yaha...@gmail.com]

I was looking at python c package and the way it extracts arguments that were sent to the procedure:
uint8_t *key;
char *in;
unsigned int i, lBuf, lKey;
PyArg_ParseTuple(args, "s#s#", &in, &lBuf, &key, &lKey)

The Tcl way is more complicated as far as I know:
Tcl_Obj * tempObj = NULL;
Tcl_ListObjIndex(interp,objv[1],0,&tempObj);
in=Tcl_GetString(tempObj)
.

Maybe I miss an elegant solution that matches the above.

In the end I did it properly with these commands:

in = Tcl_GetStringFromObj(objv[1], &lBuf);
key = Tcl_GetStringFromObj(objv[2], &lKey);

looking at it the tcl way looks cleaner :-)

Yes, that is the normal way to access variables in C.

Great,
