Interpreter providing the context for looking up or creating an object, and
into whose result error messages will be written on failure.
.AP Tcl_Obj *objPtr in
The name of the object to look up.

may be retrieved using the \fBTcl_GetObjectCommand\fR function, the name of
the object (and hence the name of the command) with \fBTcl_GetObjectName\fR,
and the namespace may be retrieved using the \fBTcl_GetObjectNamespace\fR
function. Note that the Tcl_Obj reference returned by \fBTcl_GetObjectName\fR
is a shared reference. You can also get whether the object has been marked for
deletion with \fBTcl_ObjectDeleted\fR (it returns true if deletion of the
object has begun); this can be useful during the processing of methods.
.VS "TIP 605"
The class of an object can be retrieved with \fBTcl_GetClassOfObject\fR, and
the name of the class of an object with \fBTcl_GetObjectClassName\fR; note
that these two \fImay\fR return NULL during deletion of an object (this is
transient, and only occurs when the object is a long way through being
deleted).
.VE "TIP 605"
.PP
Instances of classes are created using \fBTcl_NewObjectInstance\fR, which
creates an object from any class (and which is internally called by both
the \fBcreate\fR and \fBnew\fR methods of the \fBoo::class\fR class). It takes
parameters that optionally give the name of the object and namespace to
create, and which describe the arguments to pass to the class's constructor
(if any). The result of the function will be either a reference to the newly
