RDMA_DEREG_MR(3) Librdmacm Programmer's Manual RDMA_DEREG_MR(3)
rdma_dereg_mr - deregisters a registered memory region.
#include <rdma/rdma_verbs.h>
int rdma_dereg_mr (struct ibv_mr *mr);
mr A reference to a registered memory buffer.
Deregisters a memory buffer that had been registered for RDMA or
message operations. A user should call rdma_dereg_mr for all
registered memory associated with an rdma_cm_id before destroying
the rdma_cm_id.
Returns 0 on success, or -1 on error. If an error occurs, errno
will be set to indicate the failure reason.
All memory registered with an rdma_cm_id is associated with the
protection domain associated with the id. Users must deregister
all registered memory before the protection domain can be
destroyed.
