NAME         top

       rdma_disconnect - This function disconnects a connection.

SYNOPSIS         top

       #include <rdma/rdma_cma.h>

DESCRIPTION         top

       Disconnects a connection and transitions any associated QP to the
       error state, which will flush any posted work requests to the
       completion queue.  This routine should be called by both the
       client and server side of a connection.  After successfully
       disconnecting, an RDMA_CM_EVENT_DISCONNECTED event will be
       generated on both sides of the connection.

RETURN VALUE         top

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