Man page 9 : rio_get_asm

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

struct rio_dev * rio_get_asm(u16  vid , u16  did , u16  asm_vid , u16  asm_did , struct rio_dev *  from );

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

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.
