| // This file defines common macros that are used in protobuf. |
| // |
| // To hide these definitions from the outside world (and to prevent collisions |
| // if more than one version of protobuf is #included in the same project) you |
| // must follow this pattern when #including port_def.inc in a header file: |
| // |
| // #include "other_header.h" |
| // #include "message.h" |
| // // etc. |
| // |
| // #include "port_def.inc" // MUST be last header included |
| // |
| // // Definitions for this header. |
| // |
| // #include "port_undef.inc" |
| // |
| // This is a textual header with no include guard, because we want to |
| // detect/prohibit anytime it is #included twice without a corresponding |
| // #undef. |
| |
| // These macros are private and should always be |
| // ::util::RetrieveErrorSpace(*this) headers. If any of these errors fire, you |
| // should either properly #include port_undef.h at the end of your header that |
| // #includes port.h, or don't #include port.h twice in a .cc file. |
