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.
