IBV_ALLOC_PD(3) 					  Libibverbs Programmer's Manual					   IBV_ALLOC_PD(3)

NAME

       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 request fails.

       ibv_dealloc_pd() returns 0 on success, or the value of errno on failure (which indicates the failure reason).

NOTES

       ibv_dealloc_pd() may fail if any other resource is still associated with the PD being freed.

IBV_CREATE_AH_FROM_WC(3)				  Libibverbs Programmer's Manual				  IBV_CREATE_AH_FROM_WC(3)

NAME

       ibv_init_ah_from_wc, ibv_create_ah_from_wc - initialize or create an address handle (AH) from a work completion

SYNOPSIS

       #include <infiniband/verbs.h>

       int ibv_init_ah_from_wc(struct ibv_context *context, uint8_t port_num,
			       struct ibv_wc *wc, struct ibv_grh *grh,
			       struct ibv_ah_attr *ah_attr);

       struct ibv_ah *ibv_create_ah_from_wc(struct ibv_pd *pd,
					    struct ibv_wc *wc,
					    struct ibv_grh *grh,
					    uint8_t port_num);

DESCRIPTION

       ibv_init_ah_from_wc()  initializes  the	address handle (AH) attribute structure ah_attr for the RDMA device context context using the port
       number port_num, using attributes from the work completion wc and the Global Routing Header (GRH) structure grh.

       ibv_create_ah_from_wc() creates an AH associated with the protection domain pd using the port number port_num, using  attributes  from  the
       work completion wc and the Global Routing Header (GRH) structure grh.

RETURN VALUE

       ibv_init_ah_from_wc() returns 0 on success, and -1 on error.

       ibv_create_ah_from_wc() returns a pointer to the created AH, or NULL if the request fails.

NOTES

       The filled structure ah_attr returned from ibv_init_ah_from_wc() can be used to create a new AH using ibv_create_ah().
