ibv_modify_wq - Modify a Work Queue (WQ).

 #include <infiniband/verbs.h>  "struct int ibv_modify_wq(struct ibv_wq " "*wq,"  " struct ibv_wq_attr " "*wq_attr" ); 

ibv_modify_wq() modifys a WQ wq. The argument wq_attr is an ibv_wq_attr struct, as defined in <infiniband/verbs.h>.

struct ibv_wq_attr {
uint32_t attr_mask; /* Use enum ibv_wq_attr_mask */
enum ibv_wq_state wq_state; /* Move to this state */
enum ibv_wq_state curr_wq_state; /* Assume this is the current state */
uint32_t flags; /* Flags values to modify, use enum ibv_wq_flags */
uint32_t flags_mask; /* Which flags to modify, use enum ibv_wq_flags */
};

The function ibv_modify_wq() will modify the WQ based on the given wq_attr->attr_mask

returns 0 on success, or the value of errno on failure (which indicates the failure reason). ibv_create_wq (3), ibv_destroy_wq (3),
