## Macro Definition Documentation

#define _DBUS_GNUC_EXTENSION

Tells gcc not to warn about extensions to the C standard in the following expression, even if compiling with -pedantic.

Do not use this macro in your own code; please consider it to be internal to libdbus.

#define DBUS_BEGIN_DECLS

Macro used prior to declaring functions in the D-Bus header files.

Expands to "extern "C"" when using a C++ compiler, and expands to nothing when using a C compiler.

Please don't use this in your own code, consider it D-Bus internal.

#define DBUS_DEPRECATED

Tells the compiler to warn about a function or type if it's used.

Code marked in this way should also be enclosed in

#ifndef DBUS_DISABLE_DEPRECATED
deprecated stuff here
#endif

Please don't use this in your own code, consider it D-Bus internal.

#define DBUS_END_DECLS

Macro used after declaring functions in the D-Bus header files.

Expands to "}" when using a C++ compiler, and expands to nothing when using a C compiler.

Please don't use this in your own code, consider it D-Bus internal.
