* Name: nx_getrectangle |
|
* |
|
* Description: |
|
* Get the raw contents of graphic memory within a rectangular region. NOTE: |
|
* Since raw graphic memory is returned, the returned memory content may be |
|
* the memory of windows above this one and may not necessarily belong to |
|
* this window unless you assure that this is the top window. |
|
* |
|
* Input Parameters: |
|
* wnd - The window structure reference |
|
* rect - The location to be copied |
|
* plane - Specifies the color plane to get from. |
|
* dest - The location to copy the memory region |
|
* deststride - The width, in bytes, the the dest memory |
|
* |
|
* Return: |
|
* OK on success; ERROR on failure with errno set appropriately |
|
* |
