NAME
io_queue_wait - Wait for io requests to completeSYNOPSIS
#include <errno.h> #include <libaio.h> int io_queue_wait(io_context_t ctx_id, const struct timespec *timeout);DESCRIPTION
Attempts to read an event from the completion queue for the aio_context specified by ctx_id.RETURN VALUES
May return 0 if no events are available and the timeout specified by when has elapsed, where when == NULL specifies an infinite timeout. Note that the timeout pointed to by when is relative and will be updated if not NULL and the operation blocks. Will fail with -ENOSYS if not implemented.RETURN VALUES
On success, io_queue_wait returns 0. Otherwise, -error is return, where error is one of the Exxx values defined in the Errors section.ERRORS
EFAULT iocbs referenced data outside of the program's accessible address space. EINVAL ctx_id refers to an uninitialized aio context, the iocb pointed to by iocbs con‐ tains an improperly initialized iocb. ENOSYS Not implemented.SEE ALSO
