|
* Description:
|
|
* This function is the constructor for a raw NXTWINDOW object.
|
|
* This provides a one-to-one mapping with the window APIs in nx.h.
|
|
*
|
|
* Input Parameters:
|
|
* handle - The handle returned by nx_connect or nx_open
|
|
* cb - Callbacks used to process window events
|
|
* arg - User provided value that will be returned with NX callbacks.
|
|
*
|
|
* Return:
|
|
* Success: A non-NULL handle used with subsequent method calls
|
|
* Failure: NULL is returned and errno is set appropriately
|
|
