UMAD_GET_CA_PORTGUIDS(3) OpenIB Programmer´s Manual UMAD_GET_CA_PORTGUIDS(3)
umad_get_ca_portguids - get the InfiniBand device ports GUIDs
#include <infiniband/umad.h>
int umad_get_ca_portguids(char *ca_name, __be64 *portguids, int max);
umad_get_ca_portguids() fills the portguids array with up to max port
GUIDs belonging the specified IB device ca_name , or to the default
IB device if ca_name is NULL. The argument portguids is an array of
max uint64_t entries.
On success, umad_get_ca_portguids() returns a non-negative value
equal to the number of port GUIDs actually filled. Not all filled
entries may be valid. Invalid entries will be 0. For example, on a
CA node with only one port, this function returns a value of 2. In
this case, the value at index 0 will be invalid as it is reserved for
switches. On failure, a negative value is returned.
