linux_udev: Retry poll() on EINTR #220

Closed

rom1v wants to merge 1 commit into libusb:master from rom1v:eintr

Contributor

rom1v commented Oct 11, 2016

The poll() syscall may temporarily fail when it is interrupted by a
signal; -1 is returned and errno is set to EINTR.

When this occurred, the udev event thread exited.

Instead, since this is a temporary failure, just try the call again.

Hi,

Thanks for the patch, I've merged this manually (changing the c++ style comment to ansi-c style comment).

Regards,

Hans
