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

SYNOPSIS

       #include <infiniband/verbs.h>

       struct ibv_pd *ibv_alloc_pd(struct ibv_context *context);

       int ibv_dealloc_pd(struct ibv_pd *pd);

DESCRIPTION

       ibv_alloc_pd() allocates a PD for the RDMA device context context.

       ibv_dealloc_pd() deallocates the PD pd.

RETURN VALUE

       ibv_alloc_pd() returns a pointer to the allocated PD, or  NULL  if  the
