XAllocIconSize()														  XAllocIconSize()

Name
  XAllocIconSize - allocate an XIconSize structure.

Synopsis
  XIconSize *XAllocIconSize( )

Returns
  The allocated structure.

Availability
  Release 4 and later.

Description
  XAllocIconSize()  allocates  and  returns a pointer to an XIconSize structure, for use in calling XGetIconSizes() or XSetIconSizes().  Note
  that all fields in the XIconSize structure are initially set to zero.  If insufficient memory is available, XAllocIconSize() 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 12, Interclient Communication.

Structures
  typedef struct {
      int min_width, min_height;
      int max_width, max_height;
      int width_inc, height_inc;
  } XIconSize;
