- * Name: nxfe_constructwindow
- *
- * Description:
- * This function is the same a nx_openwindow EXCEPT that the client provides
- * the window structure instance. nx_constructwindow will initialize the
- * the pre-allocated window structure for use by NX. This function is
- * provided in addition to nx_open window in order to support a kind of
- * inheritance: The caller's window structure may include extensions that
- * are not visible to NX.
- *
- * NOTE: wnd must have been allocated using kmalloc() (or related allocators)
- * Once provided to nxfe_constructwindow() that memory is owned and managed
- * by NX. On certain error conditions or when the window is closed, NX will
- * free the window.
- *
- * Input Parameters:
- * handle - The handle returned by nx_connect
- * wnd - The pre-allocated window structure.
- * cb - Callbacks used to process window events
- * arg - User provided value that will be returned with NX callbacks.
- *
- * Return:
- * OK on success; ERROR on failure with errno set appropriately. In the
- * case of ERROR, NX will have dealloated the pre-allocated window.
