+.SH DESCRIPTION
+The
+.BR io_uring_prep_getsockname (3)
+function prepares a getsockname/getpeername request.
+The submission queue entry
+.I sqe
+is setup to fetch the locally bound address or peer address of the socket
+file descriptor pointed by
+.IR sockfd.
+The parameter
+.IR sockaddr
+points to a region of size
+.IR sockaddr_len
+where the output is written.
+.IR sockaddr_len
+is modified by the kernel to indicate how many bytes were written.
+The output address is the locally bound address if
+.IR peer
+is set to 0
+or the peer address if
+.IR peer
+is set to 1.
+
+This function prepares an async
+.BR getsockname (2)
+or
+.BR getpeername (2)
+request. See those man pages for details.
+
+.SH RETURN VALUE
+None
+.SH ERRORS
+The CQE
+.I res
+field will contain the result of the operation. See the related man page for
+details on possible values. Note that where synchronous system calls will return
+.B -1
+on failure and set
+.I errno
+to the actual error value, io_uring never uses
+.IR errno .
+Instead it returns the negated
+.I errno
+directly in the CQE
+.I res
+field.
+.BR
+Differently from the equivalent system calls, if the user attempts to
+use this operation on a non-socket file descriptor, the CQE error result
+is
+.IR ENOTSUP
+instead of
+.IR ENOSOCK.
