# Default Helper Library

## Detailed Description

This library is used to provide support for applications to be the default handler for certain services on the device.

This library is used in conjunction with Helper API from the Palm OS SDK. Typically, an application which wants to be a default app to handle certain services (SMS, Email, etc) will register itself in the following way:

- Check if the application is already the default handler for a particular service
- Call DefaultHelperLibSetDefaultHelper() if it's not already the default app. Please refer to Palm OS Helper API Service Class ID Constants for service ID.
