* Name: nxtk_setsize

|
*
|
|
* Description:
|
|
* Set the size for the selected client window. This size does not

|
|
*
|
|
* Input Parameters:
|
|
* hfwnd - The window handle returned by nxtk_openwindow
|
|
* size - The new size of the client sub-window.
|
|
*
|
|
* Returned Value:
|
|
* OK on success; ERROR on failure with errno set appropriately
