| // This file is needed for windows -- unittests are not part of the |
| // perftools dll, but still want to include config.h just like the |
| // dll does, so they can use internal tools and APIs for testing. |
| // |
| // The problem is that config.h declares PERFTOOLS_DLL_DECL to be |
| // for exporting symbols, but the unittest needs to *import* symbols |
| // (since it's not the dll). |
| // |
| // The solution is to have this file, which is just like config.h but |
| // sets PERFTOOLS_DLL_DECL to do a dllimport instead of a dllexport. |
| // |
| // The reason we need this extra PERFTOOLS_DLL_DECL_FOR_UNITTESTS |
| // variable is in case people want to set PERFTOOLS_DLL_DECL explicitly |
| // to something other than __declspec(dllexport). In that case, they |
| // may want to use something other than __declspec(dllimport) for the |
| // unittest case. For that, we allow folks to define both |
| // PERFTOOLS_DLL_DECL and PERFTOOLS_DLL_DECL_FOR_UNITTESTS explicitly. |
| // |
| // NOTE: This file is equivalent to config.h on non-windows systems, |
| // which never defined PERFTOOLS_DLL_DECL_FOR_UNITTESTS and always |
| // define PERFTOOLS_DLL_DECL to the empty string. |
