What C preprocessor conditional should I use for OS X specific code?
提问by klynch
What C preprocessor conditional should I use for OS X specific code? I need to include a specific library if I am compiling for OS X or a different header if I am compiling for Linux.
对于 OS X 特定代码，我应该使用什么 C 预处理器条件？如果我为 OS X 编译，我需要包含一个特定的库，如果我为 Linux 编译，我需要包含一个不同的头文件。
I know there is __APPLE__but I don't know if that is a current conditional for OS X 10.x.
我知道有，__APPLE__但我不知道这是否是 OS X 10.x 的当前条件。

This list of operating system macros says the presence of both__APPLE__and __MACH__indicate OSX.
此操作系统宏列表说明两者的存在__APPLE__并 __MACH__指示 OSX。
Also confirmed at line 18 of part of the source for fdisk.

__APPLE__will tell you you're compiling on an Apple platform. Unless you need to support MacOS versions before OS X, that should be good enough. Alternately, you could use __APPLE__and __MACH__to make sure you're compiling on OS X.
__APPLE__会告诉你你正在 Apple 平台上编译。除非您需要支持 OS X 之前的 MacOS 版本，否则应该足够了。或者，您可以使用__APPLE__并__MACH__确保您在 OS X 上进行编译。

If I remember correctly, it's __APPLE__:)
如果我没记错的话，是__APPLE__：）

{
//write your OSX specific code here

old style raw:
老式原始：
#ifdef WIN32
// windows.
#elif __APPLE__
// osx and ios.
#endif
