NAME         top

       umad_register - register the specified management class and
       version for port

SYNOPSIS         top

       #include <infiniband/umad.h>

       int umad_register(int portid, int mgmt_class, int mgmt_version , uint8_t rmpp_version, long method_mask[16/sizeof(long)]);

DESCRIPTION         top

       umad_register() registers the specified management class,
       management version, and whether RMPP is being used for the port
       specified by the portid parameter. If method_mask array is
       provided, the caller is registered as a replier (server) for the
       methods having their corresponding bit on in the method_mask.  If
       method_mask is NULL, the caller is registered as a MAD client,
       meaning that it can only receive replies on MADs that it sent
       (solicited MADs).

RETURN VALUE         top

       umad_register() returns non-negative agent id number on success,
       and a negative value on error as follows:
        -EINVAL invalid port handle
        -EPERM  registration failed
