# isEqualTo(const OSData *)

Tests the equality of an OSData object and the OSString instance.

## Declaration

```occ
virtual bool isEqualTo(
 const OSData *aDataObject) const; 
```

## Parameters

- `aDataObject`: An OSData object.

## Return Value

Return Value true if the two objects are equivalent, false otherwise.

## Overview

Overview This function compares the bytes of the OSData object against those of the OSString, accounting for the possibility that an OSData might explicitly include a nul character as part of its total length. Thus, for example, an OSData object containing either the bytes <'u', 's', 'b', '\0'> or <'u', 's', 'b'> will compare as equal to the OSString containing "usb".
