   If I use open () to open an existing file, how do I determine the
   filesize?  I am not attaching the file to a stream.  Here is my code:

   ---------------- cut here -------------------

   #include <unistd.h>
   #include <fcntl.h>

   int file1;        // file descriptors
   long filesize;

   void main (void)
   {
      file1 = open ("test.file", O_RDWR | O_CREAT, 0600);

   // filesize is set here...

      close (file1);
   }



Call fstat() if the file is already open and stat() before opening it.  Both
fill a struct stat buffer (to which you have passed a pointer) with file 
descriptive information.
