RIO_GET_ASM(9)                       RapidIO driver interface                      RIO_GET_ASM(9)



NAME
       rio_get_asm - Begin or continue searching for a RIO device by vid/did/asm_vid/asm_did

SYNOPSIS
       struct rio_dev * rio_get_asm(u16 vid, u16 did, u16 asm_vid, u16 asm_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

       asm_vid
           RIO asm_vid to match or RIO_ANY_ID to match all asm_vids

       asm_did
           RIO asm_did to match or RIO_ANY_ID to match all asm_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, did, asm_vid, asm_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.
