RDMA_GET_DEVICES(3) Librdmacm Programmer's Manual RDMA_GET_DEVICES(3)
rdma_get_devices - Get a list of RDMA devices currently
available.
#include <rdma/rdma_cma.h>
struct ibv_context ** rdma_get_devices (int *num_devices);
num_devices If non-NULL, set to the number of devices returned.
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.
Returns an array of available RDMA devices, or NULL if the
request fails. On failure, errno will be set to indicate the
failure reason.
The returned array must be released by calling rdma_free_devices.
Devices remain opened while the librdmacm is loaded.
