       rpma_conn_get_cq - get the connection's main CQ

SYNOPSIS

             #include <librpma.h>

             struct rpma_conn;
             struct rpma_cq;
             int rpma_conn_get_cq(const struct rpma_conn *conn, struct rpma_cq **cq_ptr);

DESCRIPTION

       rpma_conn_get_cq()  gets  the  main  CQ  from  the  connection. When the receive CQ is not
       present the main CQ allows handling  all  completions  within  the  connection.  When  the
       receive  CQ  is  present  the  main CQ allows handling all completions except rpma_recv(3)
       completions within the connection. Please see rpma_conn_get_rcq(3) for details  about  the
       receive CQ.

RETURN VALUE

       The  rpma_conn_get_cq() function returns 0 on success or a negative error code on failure.
       rpma_conn_get_cq() does not set *cq_ptr value on failure.

       rpma_conn_get_cq() can fail with the following error:

       •  RPMA_E_INVAL - conn or cq_ptr is NULL
