# nutscan\_display\_sanity\_check\_serial(3)

Display sanity check warnings about "serial" (serial number/code string) optional values in the specified \`nutscan\_device\_t\` structure on stdout.

## NAME

nutscan\_display\_sanity\_check\_serial - Display sanity check warnings about "serial" (serial number/code string) optional values in the specified \`nutscan\_device\_t\` structure on stdout.

## SYNOPSIS

```
        #include <nut-scan.h>
        void nutscan_display_sanity_check_serial(nutscan_device_t * device);
```

## DESCRIPTION

The **nutscan\_display\_sanity\_check\_serial()** function analyzes "serial" optional field in all NUT devices in *device*, and in case of duplicate or otherwise seemingly invalid values, prints comments to stdout. It displays them in a way that it can be directly copied into the ups.conf file.

It is called from **nutscan\_display\_ups\_conf\_with\_sanity\_check()** to provide an aggregate content for ups.conf file in one shot.
