Struct RecvMulti

pub struct RecvMulti { /* private fields */ }

Receive multiple messages from a socket, equivalent to recv(2).

Parameter: buf_group: The id of the provided buffer pool to use for each received message.

MSG_WAITALL should not be set in flags.

The multishot version allows the application to issue a single receive request, which repeatedly posts a CQE when data is available. Each CQE will take a buffer out of a provided buffer pool for receiving. The application should check the flags of each CQE, regardless of its result. If a posted CQE does not have the IORING_CQE_F_MORE flag set then the multishot receive will be done and the application should issue a new request.

Multishot variants are available since kernel 6.0.
