socket_share - send another socket object via a socket
#include <zircon/syscalls.h> zx_status_t zx_socket_share(zx_handle_t socket, zx_handle_t socket_to_send);
socket_share() attempts to send a new socket via an existing socket connection. The signal ZX_SOCKET_SHARE is asserted when it is possible to send a socket.
socket_share() returns ZX_OK on success. In the event of failure, one of the following values is returned.
ZX_ERR_BAD_HANDLE The handle socket or socket_to_send is invalid.
ZX_ERR_WRONG_TYPE The handle socket or socket_to_send is not a socket handle.
ZX_ERR_ACCESS_DENIED The handle socket lacks ZX_RIGHT_WRITE or the handle socket_to_send lacks ZX_RIGHT_TRANSFER.
ZX_ERR_BAD_STATE The socket_to_send was a handle to the same socket as socket or to the other endpoint of socket or the socket_to_send itself is capable of sharing.
ZX_ERR_SHOULD_WAIT There is no new socket ready to be accepted.
ZX_ERR_NOT_SUPPORTED This socket does not support the transfer of sockets. It was not created with the ZX_SOCKET_HAS_ACCEPT option.
ZX_ERR_PEER_CLOSED The socket endpoint's peer is closed.
The socket share queue is only element deep.
