>>TITLE XQueryColors Xlib7
void
XQueryColors(display, colormap, defs_in_out, ncolors)

Colormap colormap = DefaultColormap(display, DefaultScreen(display));
XColor	*defs_in_out = &dummycol;

>>EXTERN
XColor	dummycol;
>>ASSERTION Good A
A call to xname obtains the RGB values of the colourmap entries specified by the
.M pixel
components of the
.S XColor
structures named by the
.A defs_in_out
argument, and returns the RGB values in the
.M red ,
.M green ,
and
.M blue
components and sets the
.M flags
components to the bitwise OR of
.S DoRed ,
.S DoGreen ,
and
.S DoBlue .
>>STRATEGY
For each supported visual class :
  Create a colormap with XCreateColormap with alloc = AllocNone.
  Allocate a new r/o colourmap cell with XAllocColor.
  Obtain the rgb values and flags components with XQueryColors using the pixel returned by XAllocCOlor.
  Verify that the returned flags component was set to DORed|DoGreen|DoBlue.
  Verify that the rgb values are identical to those returned by XAllocColor.

>>ASSERTION Bad A
.ER BadColor
>>ASSERTION Good A
When the 
.M pixel 
component in one or more of the
.A ncolors
.S XColor
structures named by the
.A defs_in_out
argument is not a valid entry in the
.A colormap
argument, 
then a
.S BadValue
error occurs which will report any one of the
invalid pixel values.
>>STRATEGY
For each supported visual class:
  Create a colormap with XCreateColormap with alloc set to AllocNone.
  Allocate a r/o colormap cell with XAllocColor.
  Call XQueryColors with pixel array comprising pixel components 0L, -1L, -2L.
  Verify that a BadValue error occurs.
  Verify that the reported BadValue was either -1 or -2.
>>CODE BadValue
XVisualInfo 	*vp;
XColor		tcol;
XColor		qcol[3];
unsigned long	vmask;

	if((vmask = visualsupported(display, 0L)) == 0L) {
