<hr><a name="_details"></a><h2>Detailed Description</h2>
Data passed into a runtime or driver API callback function as the <code>cbdata</code> argument to <a class="el" href="group__SANITIZER__CALLBACK__API.html#gf031ccd4dcc013ab017d9ee1032858c4">Sanitizer_CallbackFunc</a>. The <code>cbdata</code> will be this type for <code>domain</code> equal to SANITIZER_CB_DOMAIN_DRIVER_API or SANITIZER_CB_DOMAIN_RUNTIME_API. The callback data is valid only within the invocation of the callback function that is passed the data. If you need to retain some data for use outside of the callback, you must make of a copy of that data. For example, if you make a shallow copy of <a class="el" href="structSanitizer__CallbackData.html" title="Data passed into a runtime or driver API callback function.">Sanitizer_CallbackData</a> within a callback, you cannot dereference <code>functionParams</code> outside of that callback to access the function parameters. <code>functionName</code> is an exception: the string pointed to by <code>functionName</code> is a global constant and so may be accessed outside of the callback. <hr><h2>Field Documentation</h2>
