RDMA_GET_DEVICES(3)					   Librdmacm Programmer's Manual				       RDMA_GET_DEVICES(3)

NAME
       rdma_get_devices - Get a list of RDMA devices currently available.

SYNOPSIS
       #include <rdma/rdma_cma.h>

       struct ibv_context ** rdma_get_devices (int *num_devices);

ARGUMENTS
       num_devices If non-NULL, set to the number of devices returned.

DESCRIPTION
       Return  a  NULL-terminated  array of opened RDMA devices.  Callers can use this routine to allocate resources on specific RDMA devices that
       will be shared across multiple rdma_cm_id's.

RETURN VALUE
       Returns an array of available RDMA devices, or NULL if the request fails.  On failure, errno will be set to indicate the failure reason.

NOTES
       The returned array must be released by calling rdma_free_devices.  Devices remain opened while the librdmacm is loaded.
