\fBTcl_FreeResult\fR performs part of the work
of \fBTcl_ResetResult\fR.
It frees up the memory associated with \fIinterp\fR's result.
It also sets \fIinterp->freeProc\fR to zero, but does not
change \fIinterp->result\fR or clear error state.
\fBTcl_FreeResult\fR is most commonly used when a procedure
is about to replace one result value with another.
.SH "THE TCL_FREEPROC ARGUMENT TO TCL_SETRESULT"
.PP
\fBTcl_SetResult\fR's \fIfreeProc\fR argument specifies how
the Tcl system is to manage the storage for the \fIresult\fR argument.
If \fBTcl_SetResult\fR or \fBTcl_SetObjResult\fR are called
at a time when \fIinterp\fR holds a string result,
they do whatever is necessary to dispose of the old string result
