Allocates or de-allocates a protection domain (PD).
#include <rdma/verbs.h> struct ibv_pd *ibv_alloc_pd(struct ibv_context *context) int ibv_dealloc_pd(struct ibv_pd *pd)
ibv_alloc_pd() allocates a PD for the RDMA device context context. ibv_dealloc_pd() de-allocates the PD pd.
context | struct ibv_context from ibv_open_device. |
ibv_alloc_pd() returns a pointer to the allocated PD, or NULL if the request fails. ibv_dealloc_pd() returns 0 on success, or the value of errno on failure (which indicates the failure reason).
