NAME

6       umad_get_ca_portguids - get the InfiniBand device ports GUIDs
7

SYNOPSIS

9       #include <infiniband/umad.h>
10
11       int umad_get_ca_portguids(char *ca_name, __be64 *portguids, int max);
12

DESCRIPTION

14       umad_get_ca_portguids()  fills  the portguids array with up to max port
15       GUIDs belonging the specified IB device ca_name , or to the default  IB
16       device  if  ca_name is NULL.  The argument portguids is an array of max
17       uint64_t entries.
18

RETURN VALUE

20       On success, umad_get_ca_portguids() returns a non-negative value  equal
21       to  the  number  of port GUIDs actually filled.  Not all filled entries
22       may be valid. Invalid entries will be 0.  For example,  on  a  CA  node
23       with  only one port, this function returns a value of 2.  In this case,
24       the value at index 0 will be invalid as it is  reserved  for  switches.
25       On failure, a negative value is returned.
