+/* The following macros are used for PLT bypassing within libc.so
+   (and if needed other libraries similarly).
+   First of all, you need to have the function prototyped somewhere,
+   say in foo/foo.h:
+
+   int foo (int __bar);
+
+   If calls to foo within libc.so should always go to foo defined in libc.so,
+   then in include/foo.h you add:
+
+   libc_hidden_proto (foo)
+
+   line and after the foo function definition:
+
+   int foo (int __bar)
+   {
+     return __bar;
+   }
+   libc_hidden_def (foo)
+
+   or
+
+   int foo (int __bar)
+   {
+     return __bar;
+   }
+   libc_hidden_weak (foo)
+
+   If foo is normally just an alias (strong or weak) of some other function,
+   you should use the normal strong_alias first, then add libc_hidden_def
+   or libc_hidden_weak:
+
+   int baz (int __bar)
+   {
+     return __bar;
+   }
+   strong_alias (baz, foo)
+   libc_hidden_weak (foo)
+
+   If the function should be internal to multiple objects, say ld.so and
+   libc.so, the best way is to use:
+
+   #if !defined NOT_IN_libc || defined IS_IN_rtld
+   hidden_proto (foo)
+   #endif
+
+   in include/foo.h and the normal macros at all function definitions
+   depending on what DSO they belong to.
+
+   If versioned_symbol macro is used to define foo,
+   libc_hidden_ver macro should be used, as in:
+
+   int __real_foo (int __bar)
+   {
+     return __bar;
+   }
+   versioned_symbol (libc, __real_foo, foo, GLIBC_2_1);
