ibv_alloc_shpd - allocate unique id for sharing a protection domain (PD).

 #include <infiniband/verbs.h>  "struct ibv_shpd *ibv_alloc_shpd(struct ibv_pd " "*pd" ", uint64_t "  " " " share_key" ", struct ibv_shpd " "*shpd"); 

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. ibv_alloc_shpd() returns shpd - a pointer to the area where the unique identifier is written - or NULL if the request fails. ibv_alloc_shpd() can be called on a particular PD only once. ibv_share_pd (3)
