+ *---------------------------------------------------------------------------

+ * Blt_InitCmd --
+ *
+ *      Given the name of a command, return a pointer to the clientData field
+ *      of the command.
+ *
+ * Results:
+ *      A standard TCL result. If the command is found, TCL_OK is returned
+ *      and clientDataPtr points to the clientData field of the command (if
+ *      the clientDataPtr in not NULL).
+ *
+ * Side effects:
+ *      If the command is found, clientDataPtr is set to the address of the
+ *      clientData of the command.  If not found, an error message is left
+ *      in interp->result.
