NAME

ibv_open_device, ibv_close_device - open and close an RDMA device context

SYNOPSIS

#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.

ibv_close_device() closes the device context context.

RETURN VALUE

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