NAME

       ibv_import_pd - import a PD from a given ibv_context

       ibv_unimport_pd - unimport a PD

SYNOPSIS

              #include <infiniband/verbs.h>

              struct ibv_pd *ibv_import_pd(struct ibv_context *context, uint32_t pd_handle);
              void ibv_unimport_pd(struct ibv_pd *pd)

DESCRIPTION

       ibv_import_pd() returns a protection domain (PD) that is associated with the given pd_handle in the given
       context.

       The  input pd_handle value must be a valid kernel handle for a PD object in the given context.  It can be
       achieved from the original PD by getting its ibv_pd->handle member value.

       The returned ibv_pd can be used in all verbs that get a protection domain.

       ibv_unimport_pd()  unimport  the  PD.   Once  the  PD  usage   has   been   ended   ibv_dealloc_pd()   or
       ibv_unimport_pd()  should  be called.  The first one will go to the kernel to destroy the object once the
       second one way cleanup what ever is needed/opposite of the import without calling the kernel.

       This is the responsibility of the application to coordinate between all ibv_context(s) that use this  PD.
       Once destroy is done no other process can touch the object except for unimport.  All users of the context
       must collaborate to ensure this.

RETURN VALUE

       ibv_import_pd() returns a pointer to the allocated PD, or NULL if the request fails.
