RIO_GET_DEVICE(9)                    RapidIO driver interface                   RIO_GET_DEVICE(9)



NAME
       rio_get_device - Begin or continue searching for a RIO device by vid/did

SYNOPSIS
       struct rio_dev * rio_get_device(u16 vid, u16 did, struct rio_dev * from);

ARGUMENTS
       vid
           RIO vid to match or RIO_ANY_ID to match all vids

       did
           RIO did to match or RIO_ANY_ID to match all dids

       from
           Previous RIO device found in search, or NULL for new search

DESCRIPTION
       Iterates through the list of known RIO devices. If a RIO device is found with a matching
       vid and did, the reference count to the device is incrememted and a pointer to its device
       structure is returned. Otherwise, NULL is returned. A new search is initiated by passing
       NULL to the from argument. Otherwise, if from is not NULL, searches continue from next
       device on the global list. The reference count for from is always decremented if it is not
       NULL.
