|
.I list_count_return
|

Returns the number of screens in the list.
|
|
.SH DESCRIPTION
|
|
.LP
|
|
This request returns a non-NULL pointer to a list of screen pointers if one or
|
|
more screens support the X Print Service Extension; otherwise it returns NULL.
|
|
|
|
XpQueryScreens determines if the X Print Service Extension is present, and if
|
|
so, which of all the screens on the X Server support the X Print Service
|
|
Extension. Unlike many other extensions, the X Print Service Extension may be
|
|
restricted to a subset of all available screens - for example, a single X Server
|
|
may be supporting video displays on some screens and printers on others.
|
|
|
|
The list of screen pointers can be freed by calling XFree.
