autosprintf: Using autosprintf

 
 3 Using 'autosprintf' in own programs
 *************************************
 
    To use the 'autosprintf' class in your programs, you need to add
 
      #include "autosprintf.h"
      using gnu::autosprintf;
 
 to your source code.  The include file defines the class 'autosprintf',
 in a namespace called 'gnu'.  The 'using' statement makes it possible to
 use the class without the (otherwise natural) 'gnu::' prefix.
 
    When linking your program, you need to link with 'libasprintf',
 because that's where the class is defined.  In projects using GNU
 'autoconf', this means adding 'AC_LIB_LINKFLAGS([asprintf])' to
 'configure.in' or 'configure.ac', and using the @LIBASPRINTF@ Makefile
 variable that it provides.
