Description
The libc crate currently exports the INADDR_ANY const to initialize a wildcard IPV4 in_addr but it doesn't provide the IPV6 counterparts as far as I can tell.
In C since in6_addr is an array instead of a single variable there are two ways to initialize a wildcard IPV6 address, the in6_addr_any global variable and the IN6ADDR_ANY_INIT macro, usually expanding to { { { 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 } } }.
I suspect that the lack of these two symbols in the libc crate is intentional since neither of them makes a lot of sense in Rust. As far as I can tell the most reasonable way to expose this feature in Rust would be:
const IN6ADDR_ANY: in6_addr = in6_addr { s6_addr: [0; 16] };But then it doesn't actually match any of the C symbols exactly.
On one hand not having this feature in the crate is not the end of the world, initializing an in6_addr with full zeroes is not hard. On the hand people coming from C/C++ will probably be surprised not to find this symbol in the crate, especially since the IPV4 counterpart does exist.
