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. #include "config.h" #undef PERFTOOLS_DLL_DECL #ifdef PERFTOOLS_DLL_DECL_FOR_UNITTESTS # define PERFTOOLS_DLL_DECL PERFTOOLS_DLL_DECL_FOR_UNITTESTS #else # define PERFTOOLS_DLL_DECL // if DLL_DECL_FOR_UNITTESTS isn't defined, use "" #endif
