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.
