NAME

       GetColorMap -- allocate and initialize Colormap

SYNOPSIS

       cm = GetColorMap( entries )
d0 d0
struct ColorMap *GetColorMap( ULONG);

FUNCTION

       Allocates, initializes and returns a pointer to a ColorMap
data structure, later enabling calls to SetRGB4/SetRGB32
and LoadRGB4/LoadRGB32 to load colors for a view port. The
ColorTable pointer in the ColorMap structure points to a
hardware specific colormap data structure. You should not
count on it being anything you can understand. Use
GetRGB4()/GetRGB32() to query it or SetRGB4CM/SetRGB32CM
to set it directly.

INPUTS

	entries - number of entries for this colormap 

RESULT

	The pointer value returned by this routine, if nonzero,
may be stored into the ViewPort.ColorMap pointer.
If a value of 0 is returned, the system was unable
to allocate enough memory space for the required
data structures.
