Wrong information in WM standard

[Frank Schmitt]

Hello,

When you look at
http://standards.freedesktop.org/wm-spec/latest/ar01s05.html#id2569669
it clearly states, that each pixel is represented by a 32 bit
integer. In fact the data type is however CARDINAL. CARDINAL is long and
long is 64 bit under Linux and therefore if you do something like

 UINT32* buffer = (UINT32*)malloc((16*16+2)*4);
 buffer[0]=w;
 buffer[1]=h;
 memset(buffer+2,0,16*16*4);
 XChangeProperty(dpy, top, net_wm_icon, cardinal, 32,
 PropModeReplace, (const unsigned char*) buffer, 2+16*16);

you get a transparent icon under 32 bit but not under 64 bit
systems. There buffer must be from a 64 bit type which contradicts the
standard.

Further on, it is totally unclear to what happens when your xserver is
on a 32 bit system and the client on a 64 bit system or vice versa.

Yours,
Frank
