Yes, I sure can work with this.
I will dissect it and make it work the way I want!
I'm amazed at this little command and how versatile it is, the reason I want to get to know it!!
Thanks very much for your help Rudic

rdma_get_recv_comp
RDMA_GET_RECV_COMP(3) Librdmacm Programmer's Manual RDMA_GET_RECV_COMP(3)
NAME
rdma_get_recv_comp - retrieves a completed receive request.
SYNOPSIS
#include <rdma/rdma_verbs.h>
int rdma_get_recv_comp (struct rdma_cm_id *id, struct ibv_wc *wc);
ARGUMENTS
id A reference to a communication identifier to check for completions.
wc A reference to a work completion structure to fill in.
DESCRIPTION
Retrieves a completed work request for a receive operation. Information about the completed request is returned through the wc parameter,
with the wr_id set to the context of the request. For details on the work completion structure, see ibv_poll_cq.
RETURN VALUE
Returns the number of returned completions (0 or 1) on success, or -1 on error. If an error occurs, errno will be set to indicate the
failure reason.
NOTES
This calls polls the receive completion queue associated with an rdma_cm_id. If a completion is not found, the call blocks until a request
completes. This call should only be used on rdma_cm_id's that do not share CQs with other rdma_cm_id's, and maintain separate CQs for
sends and receive completions.
