Tcl_SourceRCFile(interp)

Tcl_Interp *interp (in)

Tcl interpreter to source rc file into.

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.
