<p>The Extract Writer Status (QSPEXTWI) API is used by a driver program to
|
||
|
|
access information about the writer, the spooled file the writer is processing,
|
||
|
|
and to determine if the information for the spooled file has been changed. A
|
||
|
|
call to this API should be made by a driver program after each buffer is sent
|
||
|
|
to the printer.</p>
