This happens during the process of GLX initialization when we're
looking for the local DRI drivers (needed for glXGetProcAddress,
a long story).
It would be nice if Xlib could be told not to print messages like
this to stderr.
From xc/lib/X11/OpenDis.c, XOpenDisplay():
if (prefix.success != xTrue) {
/* XXX - printing messages marks a bad programming interface */
fprintf (stderr,
"Xlib: connection to \"%s\" refused by server\r\nXlib: ",
fullname);
(void) fwrite (u.failure, (Size_t)sizeof(char),
(Size_t)prefix.lengthReason, stderr);
(void) fwrite ("\r\n", sizeof(char), 2, stderr);
OutOfMemory(dpy, setup);
return (NULL);
}
David, any thoughts on adding a mechanism to Xlib to suppress these messages?
