NAME top

       manadv_init_obj - Initialize mana direct verbs object from ibv_xxx
       structures

SYNOPSIS” top

              #include <infiniband/manadv.h>

              int manadv_init_obj(struct manadv_obj *obj, uint64_t obj_type);

DESCRIPTION top

       manadv_init_obj() This function will initialize manadv_xxx structs
       based on supplied type.  The information for initialization is
       taken from ibv_xx structs supplied as part of input.

ARGUMENTS top

       obj    The manadv_xxx structs be to returned.

                  } rwq;
              };

       obj_type
              The types of the manadv_xxx structs to be returned.

              enum manadv_obj_type {
                  MANADV_OBJ_QP   = 1 << 0,
                  MANADV_OBJ_CQ   = 1 << 1,
                  MANADV_OBJ_RWQ  = 1 << 2,
              };

RETURN VALUE top

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