* 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 malloc() (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. |
