This function is used to retrieve user data that are stored as integer value,
copying the value into the 'pnUserData' pointer passed to the function as a parameter. The
function will return AEE_SUCCESS or AEE_EFAILED depending on whether or not the widget was able
to retrieve user data.
[in] Pointer to the IWidget interface object.
[out] A pointer to a int into which the widget will copy the value of the
requested user data. For example, from application, an element ID can be
associated against each widget using this user data. This Element ID is
stored as int and IWidget_GetUserData() would pass back a pointer to int,
with that pointer pointing to the element ID.
int IWidget_GetUserData(IWidget *pif, int *pnUserData);
AEE_SUCCESS : The function was able to successfully retrieve user data.
AEE_EFAILED : If the user data could not be retrieved.
