Handle completed io requests
#include <errno.h> #include <libaio.h> int io_queue_run(io_context_t ctx_id);
io_queue_run Attempts to read all the events events from the completion queue for the aio_context specified by ctx_id.
May return 0 if no events are available. Will fail with -ENOSYS if not implemented.
iocbs referenced data outside of the program's accessible address space.
ctx_id refers to an unitialized aio context, the iocb pointed to by iocbs contains an improperly initialized iocb.
