To portably implement variadic functions in the C programming language, the standard [http://www.opengroup.org/onlinepubs/009695399/basedefs/stdarg.h.html <tt><stdarg.h></tt>] header file should be used. The older [http://www.opengroup.org/onlinepubs/007908799/xsh/varargs.h.html <tt><varargs.h></tt>] header has been deprecated in favor of [http://www.opengroup.org/onlinepubs/009695399/basedefs/stdarg.h.html <tt><stdarg.h></tt>].

This allows tothe createcreation templatesof with variable number ofvariadic template parameters,classes whichand canvariadic be also used to create a function with variable number oftemplate argumentsfunctions:
