NAME

       umad_get_ca,  umad_release_ca  - get and release InfiniBand device port
       attributes

SYNOPSIS

       #include <infiniband/umad.h>

       int umad_get_ca(char *ca_name, umad_ca_t *ca);
       int umad_release_ca(umad_ca_t *ca);

DESCRIPTION

       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().

RETURN VALUE

       umad_get_ca() and umad_release_ca() return 0 on success, and a negative
       value on error.
