Description

ibv_free_device_list() frees the RDMA devices array list.

Parameters

Name Direction Description
list in RDMA device array, that was returned from ibv_get_device_list(), to free

Return Values

None (this function always succeeds).

Examples

Get device list and free it:

struct ibv_device **dev_list;
 
dev_list = ibv_get_device_list(NULL);
if (!dev_list)
        exit(1);
 
...
 
ibv_free_device_list(dev_list);
