+.SH DESCRIPTION
+.PP
+.PP
+.ZN XShmQueryExtension
+checks to see if the shared memory extensions are available for the
+specified display.
+.PP
+.ZN XShmQueryVersion
+returns the version numbers of the extension implementation. Shared
+memory pixmaps are supported if the pixmaps argument returns true.
+.PP
+.ZN XShmAttach
+tells the server to attach to your shared memory segment. If all goes
+well, you will get a non-zero status, back and your XImage is ready
+for use.
+.PP
+.ZN XShmDetach
+tells the server to detach from your shared memory segment.
+.PP
+.ZN XShmPutImage
+combines an image in memory with a shape of the specified drawable. If
+XYBitmap format is used, the depth must be one, or a ``BadMatch''
+error results. The foreground pixel in the GC defines the source for
+the one bits in the image, and the background pixel defines the source
+for the zero bits. For XYPixmap and ZPixmap, the depth must match the
+depth of the drawable, or a ``BadMatch'' error results.
+.PP
+.ZN XShmGetImage
+reads image data into a shared memory XImage where display is the
+display of interest, drawable is the source drawable, image is the
+destination XImage, x and y are offsets within the drawable, and
+plane_mask defines which planes are to be read.
+.PP
+.ZN XShmCreateImage
+allocates the memory needed for an XImage structure for the specified
+display but does not allocate space for the image itself.
+.PP
+.ZN XShmPixmapFormat
+gets the format for the server. If your application can deal with the
+server pixmap data format, a shared memory segment and shminfo
+structure are created.
+.PP
+.ZN XShmCreatePixmap
+points to a pixmap which you can manipulate in all of the usual ways,
+with the added bonus of being able to edit its contents directly
+through the shared memory segment.
+.PP
+.ZN XShmGetEventBase
+gets the completion event value.
