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.
