Libibverbs Programmer's Manual IBV_ALLOC_SHPD(3) NAME ibv_alloc_shpd - allocate unique id for sharing a protection domain (PD). SYNOPSIS #include <infiniband/verbs.h> struct ibv_shpd *ibv_alloc_shpd(struct ibv_pd *pd, uint64_t share_key, struct ibv_shpd *shpd); DESCRIPTION ibv_alloc_shpd() allocates a unique identifier required for sharing the PD pd with another process. share_key is a 64 bit key which needs to be provided with ibv_share_pd() call by another process to share the same PD in that other process. The argument shpd specifies a pointer to a user allocated area where libibverbs can write the unique identifier for the pd. RETURN VALUE ibv_alloc_shpd() returns shpd - a pointer to the area where the unique identifier is written - or NULL if the request fails.
