The function ioctl bug

[Бабенко Вячеслав]

Dear friends!

The function ioctl return -1 (errno equal 95) if I use cygwin-x86_64. See my code:
...
int fd = socket(AF_INET, SOCK_STREAM, 0);
if (ioctl(fd, FIONREAD, &c) == -1)
    printf("%u", errno);
...
The function ioctl return 0 if I use cygwin-x86.
