#include <infiniband/verbs.h>

struct ibv_context *ibv_open_device(struct ibv_device *device);

int ibv_close_device(struct ibv_context *context);
 

DESCRIPTION

ibv_open_device() opens the device device and creates a context for further use.

RETURN VALUE

ibv_open_device() returns a pointer to the allocated device context, or NULL if the request fails.
