#include <infiniband/verbs.h>

struct int ibv_modify_wq(struct ibv_wq *wq,
struct ibv_wq_attr *wq_attr);

DESCRIPTION

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
