UMAD_REGISTER(3)         OpenIB Programmer's Manual         UMAD_REGISTER(3)

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
