                       char **argv,

Description:

This function:

• Initializes the connection to the Photon Manager.
• Initializes the widget library.
• Creates a default application context (app_context) if one doesn't exist.
• Creates a main window using the num_args and args arguments--these are the same arguments passed to PtCreateWidget().

The application that calls PtAppInit() must have the appropriate permissions to read from and write to the attached Photon server, or the call will fail.

Returns:

A pointer to the main window, or NULL if an error occurs.
