Subject:	tcflush bug?
X-IsSubscribed:	yes

While debugging a clisp problem, I encountered what I think is a bug in Cygwin's tcflush.  Here's an STC:

$ cat test_tcflush.c
#include <termios.h>
#include <errno.h>
#include <string.h>
#include <stdio.h>

int
main ()
{
  if (tcflush (0, TCIFLUSH) == -1)
    fprintf (stderr, "Can't flush standard input: %s\n", strerror (errno));
  return 0;
}

$ gcc test_tcflush.c -o test_tcflush

$ ./test_tcflush.exe
Can't flush standard input: Resource temporarily unavailable

Am I misunderstanding how this should work, or is this a bug?

Ken
