Detailed Description

Policy object for wrapping default UDP operations.

Member Function Documentation

must_read_more()

static constexpr bool caf::policy::udp::must_read_more ( io::network::native_socket , size_t  )

staticconstexpr

Always returns false.

Native UDP I/O event handlers only rely on the socket buffer.

read_datagram()

bool caf::policy::udp::read_datagram ( size_t & result, io::network::native_socket fd, void * buf, size_t buf_len, io::network::ip_endpoint & ep )

static

Write a datagram containing buf_len bytes to fd addressed at the endpoint in sa with size sa_len.

Returns true as long as no IO error occurs. The number of written bytes is stored in result and the sender is stored in ep.

write_datagram()

bool caf::policy::udp::write_datagram ( size_t & result, io::network::native_socket fd, void * buf, size_t buf_len, const io::network::ip_endpoint & ep )

static

Reveice a datagram of up to len bytes.

Larger datagrams are truncated. Up to sender_len bytes of the receiver address is written into sender_addr. Returns true if no IO error occurred. The number of received bytes is stored in result (can be 0).
