Tcl_SourceRCFile — source the Tcl rc file
#include <tcl.h> void 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.
