NAME         top

       rdma_establish - Complete an active connection request.

SYNOPSIS         top

              #include <rdma/rdma_cma.h>

DESCRIPTION         top

       rdma_establish() Acknowledge an incoming connection response event
       and complete the connection establishment.

       Notes:

       If a QP has not been created on the rdma_cm_id, this function
       should be called by the active side to complete the connection,

       after getting connect response event.

       This will trigger a connection established event on the passive
       side.

       This function should not be used on an rdma_cm_id on which a QP
       has been created.

ARGUMENTS         top

       id     RDMA identifier.

RETURN VALUE         top

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