# [DESCRIPTION](#DESCRIPTION)

The [**io\_uring\_submit\_and\_get\_events**(3)](/man/os/liburing/io_uring_submit_and_get_events.3) function submits the next events to the submission queue as with [**io\_uring\_submit**(3)](/man/os/liburing/io_uring_submit.3)**.** After submission it will flush CQEs as with [**io\_uring\_get\_events**(3)](/man/os/liburing/io_uring_get_events.3)**.**

The benefit of this function is that it does both with only one system call.
