NAME¶
rdma_get_request - Retrieves the next pending connection request event.
SYNOPSIS¶
#include <rdma/rdma_cma.h>
int rdma_get_request (struct rdma_cm_id *listen,
struct rdma_cm_id **id);
ARGUMENTS¶
- listen
- Listening rdma_cm_id.
- id
- rdma_cm_id associated with the new connection.
DESCRIPTION¶
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.
NOTES¶
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.
