Function write_sockaddr_and_len

pub fn write_sockaddr_and_len(
    mem: &mut MemoryManager,
    addr: Option<&SockaddrStorage>,
    plugin_addr: ForeignPtr<u8>,
    plugin_addr_len: ForeignPtr<socklen_t>,
) -> Result<(), Errno>

Writes the socket address into a buffer at plugin_addr with length plugin_addr_len, and writes the socket address length into plugin_addr_len.

The plugin_addr_len pointer is a value-result argument, so it should be initialized with the size of the plugin_addr buffer. If the original value of plugin_addr_len is smaller than the socket address’ length, then the written socket address will be truncated. In this case the value written to plugin_addr_len will be larger than its original value.
