XmeGetPixmapData(3X) UNIX System V XmeGetPixmapData(3X)
NAME
XmeGetPixmapData - Returns details about a cached pixmap
SYNOPSIS
#include <Xm/XmP.h>
Boolean XmeGetPixmapData(
Screen *screen,
Pixmap pixmap,
char **imagename,
int *depth,
Pixel *foreground,
Pixel *background,
int *hotx,
int *hoty,
unsigned int *width,
unsigned int *height);
VERSION
This page documents Motif 2.1.
DESCRIPTION
Motif maintains a pixmap cache. This cache holds information
on the pixmaps currently in use. Use XmeGetPixmapData to
determine if a specified pixmap is currently in the pixmap
cache. If it is, XmeGetPixmapData returns the value True and
returns information for all eight of its output arguments.
If pixmap is not in the pixmap cache,
XmeGetPixmapDatafetches pixmap from the server, caches
pixmap, and then returns False. When XmeGetPixmapData
returns False, only depth, width, and height are valid.
XmeGetPixmapData is relatively efficient because it gets the
data through a table lookup rather than through a server
request.
screen Specifies a pointer to the screen.
pixmap Specifies the desired pixmap.
image_name
Returns the image name associated with pixmap.
The caller must not modify or free the returned
data.
depth Returns the depth of the pixmap.
foreground
Returns the foreground color associated with
pixmap.

background
Returns the background color associated with
pixmap.
hot_x Returns the x-coordinate of the hotspot of
pixmapif hotspot information was stored with the
pixmap.
hot_y Returns the y-coordinate of the hotspot of
pixmapif hotspot information was stored with the
pixmap.
width Returns the width of pixmap.
height Returns the height of pixmap.
RETURN
Returns True if pixmap is in the image cache. Otherwise, it
returns False.
