UMAD_GET_CA(3) OpenIB Programmer´s Manual UMAD_GET_CA(3)
umad_get_ca, umad_release_ca - get and release InfiniBand device port
attributes
#include <infiniband/umad.h>
int umad_get_ca(char *ca_name, umad_ca_t *ca);
int umad_release_ca(umad_ca_t *ca);
umad_get_ca() gets the attributes of the InfiniBand device ca_name.
It fills the ca structure with the device attributes specified by the
ca_name or with the default device attributes if ca_name is NULL.
umad_release_ca() should be called before the ca structure is
deallocated. The argument ca is an umad_ca_t struct, as specified in
<infiniband/umad.h>.
typedef struct umad_ca {
char ca_name[UMAD_CA_NAME_LEN]; /* Name of the device */
uint node_type; /* Type of the device */
int numports; /* Number of physical ports */
char fw_ver[20]; /* FW version */
char ca_type[40]; /* CA type (e.g. MT23108, etc.) */
char hw_ver[20]; /* Hardware version */
uint64_t node_guid; /* Node GUID */
uint64_t system_guid; /* System image GUID */
umad_port_t *ports[UMAD_CA_MAX_PORTS]; /* Array of device port properties */
} umad_ca_t;
umad_release_ca() releases the resources that were allocated in the
function umad_get_ca().
umad_get_ca() and umad_release_ca() return 0 on success, and a
negative value on error.
