XdbeGetVisualInfo(3) X FUNCTIONS XdbeGetVisualInfo(3)NAME
XdbeGetVisualInfo - Get dbe Visual Informations
SYNOPSIS
#include <X11/extensions/Xdbe.h>
XdbeScreenVisualInfo *XdbeGetVisualInfo(
Display *dpy,
Drawable *screen_specifiers,
int *num_screens)
DESCRIPTION
This function returns information about which visuals support double buffering. The argument num_screens specifies how many elements there
are in the screen_specifiers list. Each drawable in screen_specifiers designates a screen for which the supported visuals are being
requested. If num_screens is zero, information for all screens is requested. In this case, upon return from this function, 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 XdbeScreenVisualInfo structures of length num_screens. The nth element in the returned list corresponds to the nth drawable in the
screen_specifiers list, unless num_screens was passed in with the value zero, in which case the nth element in the returned list corre-
sponds to the nth screen of the server, starting with screen zero. The XdbeScreenVisualInfo structure has the following fields:
int count
XdbeVisualInfo *visinfo
count specifies the number of items in visinfo. visinfo specifies a list of visuals, depths, and performance hints for this screen.
The XdbeVisualInfo structure has the following fields:
VisualID visual
int depth
int perflevel
visual specifies one visual ID that supports double-buffering. depth specifies the depth of the visual. perflevel is a performance hint.
The only operation defined on a perflevel is comparison to a perflevel of another visual on the same screen. The visual having the higher
perflevel is likely to have better double-buffering graphics performance than the visual having the lower perflevel. Nothing can be
deduced from the following: the magnitude of the difference of two perflevels, a perflevel value in isolation, or comparing perflevels from
different servers.
ERRORS
BadDrawable
One or more values passed in screen_specifiers is not a valid drawable.

I'm looking for finer granularity than the 20 ANSI escape sequence screen modes. What I'd like to do is have the terminal increase it's own height when I have to show the user a long menu.
Platform is Cygwin 64 running over Win 7 Pro.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
