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.
