IBV_ALLOC_PD(3) Libibverbs Programmer's Manual IBV_ALLOC_PD(3)

ibv_alloc_pd, ibv_dealloc_pd - allocate or deallocate a protection domain (PDs)

#include <infiniband/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() deallocates the PD pd.

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).

ibv_dealloc_pd() may fail if any other resource is still associated with the PD being freed.
