+.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
+DBE,
