XAllocClassHint()					     XAllocClassHint()

Name
  XAllocClassHint – allocate an XClassHint structure.

Synopsis
  XClassHint *XAllocClassHint( )

Returns
  The allocated structure.

Availability
  Release 4 and later.

Description
  XAllocClassHint()  allocates	and  returns  a	 pointer to an XClassHint
  structure, for use in calling XSetWMProperties(),  XGetClassHint(),  or
  XSetClassHint().  Note that the pointer fields in the XClassHint struc‐
  ture are initially set to NULL.  If insufficient memory  is  available,
  XAllocClassHint()  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	 Communi‐
  cation.

Structures
  typedef struct {
      char *res_name;
      char *res_class;
  } XClassHint;
