条件编译常量定义约定：
|
|
|
|
|
|
(1) Windows操作系统: OS_WINDOWS
|
|
|
|
|
|
(2) Unix(统称)操作系统: OS_UNIX
|
|
|
(3) Linux操作系统: _OS_UNIX_LINUX_
|
|
|
(4) True64操作系统: _OS_UNIX_TRUR64_
|
|
|
(5) Solaris操作系统: _OS_UNIX_SOLARIS_
|
|
|
|
|
|
(6) 64位操作系统: _OS_64BIT_
|
|
|
|
|
|
(7) Windows字节顺序: _OS_WINDOWS_BYTEORDER_
|
|
|
(8) Solaris字节顺序: _OS_SOLARIS_BYTEORDER_
|
|
|
|
|
|
[说明]：
|
|
|
|
|
|
a. 64位操作系统主要有：DEC True64, solaris(有时可能是32位系统,可以通过测试sizeof
|
|
|
(long)是否=8来判断)
|
|
|
|
|
|
b. windows, linux, true64 等操作系统的字节顺序和solaris相反,因此分别以Windows
|
|
|
和solaris为代表定义不同的字节顺序
|
|
|
|
|
|
c. Unix操作系统种类繁多，每个变种有一定的差别，因此为常见的unix系统每种定义一个
