**void io\_uring\_prep\_send\_set\_addr(struct io\_uring\_sqe \****sqe***,**                                  **const struct sockaddr \****dest\_addr***,**                                  **\_\_u16** *addr\_len***);**

## DESCRIPTION

The [**io\_uring\_prep\_send\_set\_addr**(3)](/io_uring_prep_send_set_addr/3.md) function sets a socket destination address specified by *dest\_addr* and its length using *addr\_len* parameters. It can be used once  *sqe* is prepared using any of the [**send**(2)](/send/2.md) io\_uring helpers. See man pages of [**io\_uring\_prep\_send**(3)](/io_uring_prep_send/3.md) or [**io\_uring\_prep\_send\_zc**(3)](/io_uring_prep_send_zc/3.md).
