Option /P: Preprocessed output -> UNIX-Style-Textfiles

[fuerst]

Assume following C-Source simple.c

Code Select Expand

#define RETVAL 0
int main( void )
{
  return RETVAL;
}

Generating preprocessoroutput from simple.c with option /P

pocc /P simple.c

generates the file simple.i, which has no CR/LF-Ending. If you open such a file in Windows-Notepad, you see _one_ long line. Below hexdump-Output.

Just use a proper editor that doesn't choke on the line endings. The dump shows that the file has *ix style LF-only file endings, pretty much any other file editor BUT Notepad will open those just fine... (Hint: Try PSPad)

My intention is not to discuss about texteditors but to give the hint, that the outputfile has a unusual format.

Well, my intention was to point out that the format is anything but unusual...
