rdma_migrate_id - Move a communication identifier to a different event channel. "#include <rdma/rdma_cma.h>"

"int" rdma_migrate_id "(struct rdma_cm_id *" id "," "struct rdma_event_channel *" channel ");"

An existing communication identifier to migrate. The communication channel that events associated with the allocated rdma_cm_id will be reported on. May be NULL. Migrates a communication identifier to a different event channel. Returns 0 on success, or -1 on error. If an error occurs, errno will be set to indicate the failure reason. This routine migrates a communication identifier to the specified event channel and moves any pending events associated with the rdma_cm_id to the new channel. Users should not poll for events on the rdma_cm_id's current event channel or invoke other routines on the rdma_cm_id while migrating between channels. This call will block while there are any unacknowledged events on the current event channel.

If the channel parameter is NULL, the specified rdma_cm_id will be placed into synchronous operation mode. All calls on the id will block until the operation completes.
