Message-ID: <47c554d90910201458of5dc16eg33940584026bc959@mail.gmail.com> Date: Tue, 20 Oct 2009 14:58:17 -0700 From: Zubin Dittia <zubin@...tri.com> To: linux-kernel@...r.kernel.org Subject: libaio asynchronous syscall io_getevents blocks on error I'm writing a program that uses the kernel's io_submit/io_getevents system calls. What I would like to be able to do is submit N operations for i/o on different files, and then call io_getevents with min_nr = nr = N and a timeout of NULL, so that I can block until all N operations have completed. This works great, except when one of the operations has an error (eg., if one of the descriptors is invalid). In this case, the call to io_getevents appears to block indefinitely. Shouldn't an error on one of the submitted operations count as a completion event for that operation, so I can check the error code when the call returns? Any help would be appreciated.
