The Linux 2.4 Parallel Port Subsystem | ||
---|---|---|
<<< Previous | Next >>> |
This walks through the list of parallel port devices looking for a device whose 'CLS' string matches cls in their IEEE 1284 Device ID.
When a device is found matching those requirements, its device number is returned; if there is no matching device, a negative value is returned.
A new search it initiated by passing NULL
as the from
argument. If from is not NULL
, the search continues from
that device.
