Subject: bindings: cxx: add a missing throw to line::event_get_fd()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d001dde47cc0df44ad79aa19bfe5bafaf4ba31bd;p=qemu-gpiodev%2Flibgpiod.git

bindings: cxx: add a missing throw to line::event_get_fd()

If the call to gpiod_line_event_get_fd() fails, we're not actually
throwing the exception - we're only creating it on stack. Add the
missing throw keyword.

Fixes: 8078a4a2ad90 ("bindings: implement C++ bindings")
