SYNOPSIS

10       #include <ggi/gii.h>`
11
12       int giiQueryDeviceInfo (gii_input_t inp, uint32_t origin,
13                               gii_cmddata_getdevinfo *info);
14
15       int giiQueryDeviceInfoByNumber(gii_input_t inp, uint32_t number,
16                                      uint32_t *origin, gii_cmddata_getdevinfo *info);

DESCRIPTION

20       Though when using GII inputs the exact type of device is  fully  trans‐
21       parent  to  the  program, information about the device that is actually
22       attached to a given gii input and origin id can be  queried,  e.g.  for
23       configuration interfaces.
24
25       For  giiQueryDeviceInfo  the parameters inp and origin select the input
26       to query. This version is usually used,  if  you  want  to  identify  a
27       device after getting an event from it.
28
29       For giiQueryDeviceInfoByNumber the parameters inp and number select the
30       input to query - origin gets set to the origin ID  the  queried  device
31       has. This version is used, when you want to query all known devices.
32
33       The  queried  data is put into info.  See gii_cmddata_getdevinfo(3) for
34       the description of the structure.

RETURN VALUE

37       Returns 0 on success (info is valid, then) or -1 otherwise.
