c++ - 如何在编译时检测WP8

Question

我正在开发一个跨平台的 C++ 库。我的目标是 WP8，我需要检测目标是 WP8 还是桌面 Windows。

是否有为 WP8 目标自动设置的标志？

我考虑过使用 _WIN32，但它似乎在两个平台上都有定义。

不确定这是否是您要查找的内容，但如果您正在做一个通用应用程序/可移植库，您可以使用

/*
 * When compiling C and C++ code using SDK header files, the development
 * environment can specify a target platform by #define-ing the
 * pre-processor symbol WINAPI_FAMILY to one of the following values.
 * Each FAMILY value denotes an application family for which a different
 * subset of the total set of header-file-defined APIs are available.
 * Setting the WINAPI_FAMILY value will effectively hide from the
 * editing and compilation environments the existence of APIs that
 * are not applicable to the family of applications targeting a
 * specific platform.

#define WINAPI_FAMILY_PC_APP      2     /* Windows Store Applications */
#define WINAPI_FAMILY_PHONE_APP   3     /* Windows Phone Applications */
#define WINAPI_FAMILY_DESKTOP_APP 100   /* Windows Desktop Applications */
