# giiQueryValInfo(3)

Get data about valuators

## NAME

**giiQueryValInfo** - Get data about valuators

## SYNOPSIS

```
#include <ggi/gii.h>
int giiQueryValInfo(gii_input_t inp, uint32_t origin,
                    uint32_t valnumber, gii_cmddata_getvalinfo *info);
```

## DESCRIPTION

Though when using GII inputs the exact type of device is fully transparent to the program, information about the device that is actually attached to a given gii input and origin id can be queried, e.g. for configuration interfaces.

For **giiQueryValInfo** is used on devices, where **[giiQueryDeviceInfo(3)](/giiQueryDeviceInfo/3.md)** has indicated that the device has one or more valuator axes and you want to gather additional info about the physical equivalent of each axis.The parameters *inp* and *origin* select the input to query and *valnumber* selects the specific valuator (an input can have multiple valuators).

The queried data is put into *info*.  See `gii_cmddata_getvalinfo(3)` for the description of the structure.

## RETURN VALUE

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