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.
