* Name: nxtk_gettoolbar
|
|
*
|
|
* 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, of the dest memory
|
|
*
|
|
* Returned Value:
|
|
* OK on success; ERROR on failure with errno set appropriately
|
|
