rdma_leave_multicast - Leaves a multicast group.
#include <rdma/rdma_cma.h>
int rdma_leave_multicast (struct rdma_cm_id
*id, struct sockaddr *addr);
- id
- Communication identifier associated with the request.
- addr
- Multicast address identifying the group to leave.
Leaves a multicast group and detaches an associated QP from the group.
Returns 0 on success, or -1 on error. If an error occurs, errno will be set to
indicate the failure reason.
Calling this function before a group has been fully joined results in canceling
the join operation. Users should be aware that messages received from the
multicast group may stilled be queued for completion processing immediately
after leaving a multicast group. Destroying an rdma_cm_id will automatically
leave all multicast groups.
