ibv_alloc_pd, ibv_dealloc_pd

Allocates or de-allocates a protection domain (PD).

Syntax

#include <rdma/verbs.h>
struct ibv_pd *ibv_alloc_pd(struct ibv_context *context)
int ibv_dealloc_pd(struct ibv_pd *pd)

Description

ibv_alloc_pd() allocates a PD for the RDMA device context context. ibv_dealloc_pd() de-allocates the PD pd.

Note: ibv_dealloc_pd() might fail if any other RDMA resource is still associated with the PD being freed.

Parameters

context struct ibv_context from ibv_open_device.

Return Value

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).
