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.
