Detailed Description

Policy object for wrapping default TCP operations.

Member Function Documentation

must_read_more()

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

staticconstexpr

Always returns false.

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

read_some()

rw_state caf::policy::tcp::read_some ( size_t & result, io::network::native_socket fd, void * buf, size_t len )

static

Reads up to len bytes from fd, writing the received data to buf.

Returns true as long as fd is readable and false if the socket has been closed or an IO error occurred. The number of read bytes is stored in result (can be 0).

try_accept()

bool caf::policy::tcp::try_accept ( io::network::native_socket & result, io::network::native_socket fd )

static

Tries to accept a new connection from fd.

On success, the new connection is stored in result. Returns true as long as

write_some()

rw_state caf::policy::tcp::write_some ( size_t & result, io::network::native_socket fd, const void * buf, size_t len )

static

Writes up to len bytes from buf to fd.

Returns true as long as fd is readable and false if the socket has been closed or an IO error occurred. The number of written bytes is stored in result (can be 0).
