As a special service "Fossies" has tried to format the requested source page into HTML format using (guessed) C and C++ source code syntax highlighting (style: standard) with prefixed line numbers and code folding option. Alternatively you can here view or download the uninterpreted source code file.

    2  run ncc on this file, with : ncc farg.c

    6  The new thing is the new output directive 'R'
    7  
    8  R: A B
    9  
   10  Should be interpreted by nccnav that the callers of 'A' do not
   11  really call 'A' but 'B'. This is a "replacement" directive.
