Colormap issues

[Dennie, Brooke]

Hi everyone,

I'm a little confused as to how the following code can produce the
output:

succeeded... 15736992 256

gdk_color_parse("green", &color);
if(gdk_colormap_alloc_color(colormap, &color, FALSE, TRUE))
  printf("succeeded... %d %d\n", color.pixel, colormap->size);


The pixel value is obviously causing a few problems later on when
I try to query the color. I had been under the impression that
the printf statement wouldn't be executed unless the pixel value
had been filled in. Is this not the case?

Thanks for any info!

Unless you are really running this on an 8bit pseudo-color display,
this output doesn't look particulary suspicious to me. The expected
result depends on the visual of the colormap but you aren't supposed
to care about this at all.
