linux_udev: Retry poll() on EINTR #220
Closed
Conversation
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. <https://www.gnu.org/software/libc/manual/html_node/Interrupted-Primitives.html> Signed-off-by: Romain Vimont <rom@rom1v.com>

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