File Content Extraction 25.2
Filter SDK C++ Programming Guide

# Exceptions

All of the C++ API methods can throw exceptions. File Content Extraction errors take the form of an instance of `keyview_error`, which is itself derived from `std::exception`. The exceptions that can be thrown are defined in `Keyview_Errors.hpp`.

In application code, it is possible to catch and correctly handle many of these exceptions. For example, while processing many files, a `format_not_supported_error` might be thrown. The correct behavior for an application might be to skip this file, or to add it to a list of files that could not be recognized. Similarly, if a `password_protected_error` is thrown and caught, an application might prompt a user to enter a password and then retry.
