rdma_get_request — Retrieves the next pending connection request event.


#include <rdma/rdma_cma.h>

int rdma_get_request (struct rdma_cm_id *listen, struct rdma_cm_id **id);



Listening rdma_cm_id.


rdma_cm_id associated with the new connection.


Retrieves a connection request event.  If no requests are pending, the call will block until an event is received.

Return Value

Returns 0 on success, or -1 on error.  If an error occurs, errno will be set to indicate the failure reason.


This call may only be used on listening rdma_cm_id's operating synchronously.  On success, a new rdma_cm_id representing the connection request will be returned to the user.  The new rdma_cm_id will reference event information associated with the request until the user calls rdma_reject, rdma_accept, or rdma_destroy_id on the newly created identifier.  For a description of the event data, see rdma_get_cm_event.

If QP attributes are associated with the listening endpoint, the returned rdma_cm_id will also reference an allocated QP.
