.SH DESCRIPTION
|
|
.LP
|
|
XpQueryExtension determines if the X Print Service Extension is present. It
|
|
returns True if the extension is supported, otherwise False. If the extension is
|
|
present, the base values for events and errors are returned, and can be used to
|
|
decode incoming event and error values.
|
|
|
|
The X Print Service Extension is initialized on the first call to any X Print
|
|
Service function; there is no need to explicitly initialize the X Print Service
|
|
Extension.
