corresponding arguments given to \fBTcl_CreateTrace\fR.
\fIClientData\fR typically points to an application-specific data
argument substitution. The \fIcommandToken\fR parameter is a Tcl
command token that identifies the command to be invoked. The token
may be passed to \fBTcl_GetCommandName\fR,

parameters designate the final parameter count and parameter vector
that will be passed to the command, and have had all substitutions
