#include "libc/sysv/consts/syscon.internal.h"
Support non-blocking i/o across platforms This change introduces new tests for `O_NONBLOCK` and `SOCK_NONBLOCK` to confirm that non-blocking i/o is now working on all supported platforms, including Windows. For example, you can now say on Windows, MacOS, etc.: socket(AF_INET, SOCK_STREAM | SOCK_NONBLOCK, IPPROTO_TCP); To create a non-blocking IPv4 TCP socket. Or you can enable non-blocking i/o on an existing socket / pipe / etc. file descriptor by calling fcntl fcntl(fd, F_SETFL, fcntl(fd, F_GETFL) | O_NONBLOCK); This functionality is polyfilled on older Linux kernels too, e.g. RHEL5. Now that fcntl() support is much better the FIOCLEX / FIONCLEX polyfills for ioctl() have been removed since they're ugly non-POSIX diameond APIs This change fixes a weakness in kprintf() that was causing Windows trace tools to frequently crash.
