Libibverbs Programmer's Manual IBV_GET_DEVICE_LIST(3)
NAME
ibv_get_device_list, ibv_free_device_list - get and release list of
available RDMA devices
SYNOPSIS
#include <infiniband/verbs.h>
struct ibv_device **ibv_get_device_list(int *num_devices);
void ibv_free_device_list(struct ibv_device **list);
DESCRIPTION
ibv_get_device_list() returns a NULL-terminated array of RDMA devices
currently available. The argument num_devices is optional; if not
NULL, it is set to the number of devices returned in the array.
ibv_free_device_list() frees the array of devices list returned by
ibv_get_device_list().
RETURN VALUE
ibv_get_device_list() returns the array of available RDMA devices, or
sets errno and returns NULL if the request fails. If no devices are
found then num_devices is set to 0, and non-NULL is returned.
ibv_free_device_list() returns no value.
ERRORS
EPERM Permission denied.
ENOSYS No kernel support for RDMA.
ENOMEM Insufficient memory to complete the operation.
ATTRIBUTES
See attributes(7) for descriptions of the following attributes:
+---------------+-----------------------+
|ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+---------------+-----------------------+
|Availability | network/open-fabrics |
+---------------+-----------------------+
|Stability | Pass-through volatile |
+---------------+-----------------------+
NOTES
Client code should open all the devices it intends to use with
ibv_open_device() before calling ibv_free_device_list(). Once it frees
the array with ibv_free_device_list(), it will be able to use only the
open devices; pointers to unopened devices will no longer be valid.
