IBV_OPEN_DEVICE(3)      Libibverbs Programmer's Manual      IBV_OPEN_DEVICE(3)



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.

       ibv_close_device() returns 0 on success, -1 on failure.

NOTES
       ibv_close_device()  does  not  release  all  the  resources allocated using context context.  To avoid resource
       leaks, the user should release all associated resources before closing a context.
