- In the case of the `host` application [1], the `host` app uses `libuv` to perform the DNS lookup. - `uv__udp_sendmsg` uses the `syscall` to perform the sending message operation. The decision of whether to use `syscall` or `sendmsg` is based on checking the value of the `uv__sendmmsg_avail` variable in `uv__udp_sendmsg` [2]. - `uv__udp_recvmsg` uses `recvmsg` to perform the receiving message operation. The decision of whether to use `syscall` or `recvmsg` is based on checking the result of `uv_udp_using_recvmmsg` [3]. - The above explains why `libuv` uses `syscall` for sending messages and `recvmsg` for receiving messages. - Additionally `libuv` check support for `recvmmsg()` and `sendmmsg()` using `uv__udp_mmsg_init` with calling `uv__sendmmsg(s, NULL, 0, 0)` [4] The stack traces for the and `uv__udp_sendmsg` and `uv__udp_recvmsg`: ``` [#0] syscall() [#1] uv__sendmmsg(...) [#2] uv__udp_sendmmsg(..) [#3] uv__udp_sendmsg(...) [#4] uv__udp_send(...) [#5] uv_udp_send(...) ``` ``` [#0] recvmsg [#1] uv__udp_recvmsg ``` Ref: [1] https://github.com/isc-projects/bind9 [2] libuv/libuv@3d71366 [3] libuv/libuv@6b5aa66 [4] libuv/libuv@3d71366 Closes: #1586
