NAME

GetColorMap -- allocate and initialize Colormap

SYNOPSIS

    cm = GetColorMap( entries )
          d0                   d0

    struct ColorMap *GetColorMap( ULONG);

Links: ColorMap

FUNCTION

Allocates, initializes and returns a pointer to a ColorMap data structure, later enabling calls to SetRGB4 and LoadRGB4 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 to query it or SetRGB4CM 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.
