-.TH XdbeGetVisualInfo __libmansuffix__ __xorgversion__ "X FUNCTIONS"
-.SH NAME
-XdbeGetVisualInfo - Get dbe Visual Informations
-.SH SYNOPSIS
-\&#include <X11/extensions/Xdbe.h>
-
-XdbeScreenVisualInfo *XdbeGetVisualInfo(
- Display *dpy,
- Drawable *screen_specifiers,
- int *num_screens)
-.SH DESCRIPTION
-This function returns information about which visuals support double
-buffering. The argument
-.I num_screens
-specifies how many elements there are
-in the
-.I screen_specifiers
-list. Each drawable in
-.I screen_specifiers
-designates a
-screen for which the supported visuals are being requested. If
-.I num_screens
-is zero, information for all screens is requested. In this case, upon return
-from this function,
-.I num_screens
-will be set to the number of screens that were
-found. If an error occurs, this function returns NULL, else it returns a
-pointer to a list of
-.I XdbeScreenVisualInfo
-structures of length
-.I num_screens.
-The nth
-element in the returned list corresponds to the nth drawable in the
-.I screen_specifiers
-list, unless
-.I num_screens
-was passed in with the value zero,
-in which case the nth element in the returned list corresponds to the nth screen
-of the server, starting with screen zero. The
-.I XdbeScreenVisualInfo
-structure has the following fields:
-
- int count
- XdbeVisualInfo *visinfo
-
-.I count
-specifies the number of items in
-.I visinfo.
-.I visinfo
-specifies a list of visuals, depths, and performance hints for this screen.
-
-The
-.I XdbeVisualInfo
-structure has the following fields:
-
- VisualID visual
- int depth
- int perflevel
-
-.I visual
-specifies one visual ID that supports double-buffering.
-.I depth
-specifies the depth of the visual.
-.I perflevel
-is a performance hint.
-
-The only operation defined on a
-.I perflevel
-is comparison to a
-.I perflevel
-of another visual on the same screen. The visual having the higher
-.I perflevel
-is likely to have better double-buffering graphics performance than the visual
-having the lower
-.I perflevel.
-Nothing can be deduced from the following: the magnitude of the difference
-of two
-.I perflevels,
-a
-.I perflevel
-value in isolation, or comparing
-.I perflevels
-from different servers.
-
-.SH ERRORS
-.IP BadDrawable
-One or more values passed in
-.I screen_specifiers
-is not a valid drawable.
-.SH SEE ALSO
