i'm attempting to put together a simple test that creates a window, allocates a buffer in memory and using an XImage and XShmPutImage () displays it on my screen. i have a tiny piece of code that (as far as i know) does all the right things - it creates the window but when i try to display the contents of my buffer via an XImage i get a message like this: X Error of failed request: BadAccess (attempt to access private resource denied) Major opcode of failed request: 144 (MIT-SHM) Minor opcode of failed request: 3 (X_ShmPutImage) i've seen this type of problem described in the newsgroups but there don't seem to be any answers posted. i check the return from all my previous calls and they're fine. i'm using XFree86 version 4.3.0 (27 feb 2003), X Protocol version 11, rev 0, rel 6.6 and my OS is NetBSD/i386 1.6 [elf]. can anyone shed any light on this please? thanks. cp _______________________________________________ XFree86 mailing list XFree86@xxxxxxxxxxx http://XFree86.Org/mailman/listinfo/xfree86
