Limit on number of open files

[Edward Deitz <endeitz at yahoo dot com>]

Is there a way to increase the number of files that
can be open simultaneously?  Here's what I've tried:

$ ulimit -n 1024
$ ulimit -n
1024

So I tested with the following code:

#include <stdio.h>
int
main(int argc, char **argv)
{
  int i;
  for (i = 0; i < 1000; i++)
    {
      FILE *f = fopen("/dev/null", "r");
      if (!f)
	break;
      printf("%d\n", i);
    }
  exit(0);
}

Results:

0
1
...
132
Segmentation fault (core dumped)

So the limit appears to be 133 files.  And it appears
to have no relation to the ulimit command (which is
probably intentional, I'm not sure if ulimit is
supposed to work in Cygwin).

Any ideas, anyone?

Ed.
