ibv_open_device, ibv_close_device - open and close an RDMA device context

SYNOPSIS DESCRIPTION RETURN VALUE NOTES SEE ALSO AUTHORS

#include <infiniband/verbs.h> 

struct ibv_context *ibv_open_device(struct ibv_device *device"); 

int ibv_close_device(struct ibv_context *context"); 

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

ibv_close_device() closes the device context context.

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.

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.
