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. +.PP +.SH SEE ALSO +\fIMIT-SHM - The MIT Shared Memory Extension \fP diff --git a/libXext/src/XShm.c b/libXext/src/XShm.c index cffd30756..d1f1a4d7f 100644 --- a/libXext/src/XShm.c +++ b/libXext/src/XShm.c @@ -1,431 +1,431 @@ -/* - * -Copyright 1989, 1998 The Open Group - -Permission to use, copy, modify, distribute, and sell this software and its -documentation for any purpose is hereby granted without fee, provided that -the above copyright notice appear in all copies and that both that -copyright notice and this permission notice appear in supporting -documentation. - -The above copyright notice and this permission notice shall be included in -all copies or substantial portions of the Software. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR -IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, -FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
