\fBTcl_AppendObjToErrorInfo\fR is an alternative interface to the
same functionality as \fBTcl_AddErrorInfo\fR. \fBTcl_AppendObjToErrorInfo\fR
is called when the string value to be appended to the \fB\-errorinfo\fR option
is available as a \fBTcl_Obj\fR instead of as a \fBchar\fR array.

\fBTcl_AddObjErrorInfo\fR is nearly identical
