XAllocStandardColormap()			      XAllocStandardColormap()

Name
  XAllocStandardColormap – allocate an XStandardColormap structure.

Synopsis
  XStandardColormap *XAllocStandardColormap( )

Returns
  The allocated structure.

Availability
  Release 4 and later.

Description
  XAllocStandardColormap()  allocates  and returns a pointer to an XStan‐
  dardColormap structure for use in calling XGetRGBColormaps() or XSetRG‐
  BColormaps().	  Note that all fields in the XStandardColormap structure
  are initially set to zero.  If insufficient memory is	 available,  XAl‐
  locStandardColormap()	 returns  NULL.	  To free the memory allocated to
  this structure, use XFree().

  The purpose of this function is to avoid compiled-in	structure  sizes,
  so that object files will be binary compatible with later releases that
  may have new members added to structures.

  For more information, see Volume One, Chapter 7, Color.
