// libbinder is built with symbol hidden by default. To add a new symbol to the
// ABI, you must annotate it with this LIBBINDER_EXPORTED macro. When not
// building libbinder (e.g. when another binary includes a libbinder header),
// this macro is a no-op.
//
// Examples:
//
// // Export a function.
// LIBBINDER_EXPORTED void someFunction();
//
// // Export a subset of the symbols for a class.
// class SomeClassA {
// public:
// LIBBINDER_EXPORTED SomeClassA();
//
// LIBBINDER_EXPORTED SomeMethod();
// }
//
// // Export all the symbols for a class, even private symbols.
// class LIBBINDER_EXPORTED SomeClassB {};
//
// For a more detailed explanation of this strategy, see
// https://www.gnu.org/software/gnulib/manual/html_node/Exported-Symbols-of-Shared-Libraries.html
#if BUILDING_LIBBINDER
#define LIBBINDER_EXPORTED __attribute__((__visibility__("default")))
#else
#define LIBBINDER_EXPORTED
#endif
// For stuff that is exported but probably shouldn't be. It behaves the exact
// same way as LIBBINDER_EXPORTED, only exists to help track what we want
// eventually remove.
//
// Needed, at least in part, because the test binaries are using internal
// headers and accessing these symbols directly.
