DESCRIPTION
       Tcl_SourceRCFile  is  used  to  source  the  Tcl rc file at startup.  It is typically invoked by Tcl_Main or Tk_Main.  The name of the file
       sourced is obtained from the global variable tcl_rcFileName in the interpreter given by interp.  If this variable is not defined, or if the
       file it indicates cannot be found, no action is taken.
