如何在 C++ 中设置环境变量？

• 他们不需要坚持过去的程序执行
• 它们只需要在当前进程中可见
• 偏好平台独立，但我的问题只需要在 Win32/64 上工作

谢谢

NAME

       putenv - change or add an environment variable

SYNOPSIS

       #include <stdlib.h>

       int putenv(char *string);

DESCRIPTION
       The  putenv()  function adds or changes the value of environment
       variables.  The argument string is of the form name=value.  If name does
       not already exist in the environment, then string is added  to  the
       environment.   If name does exist, then the value of name in the
       environment is changed to value.  The string pointed to by string becomes
       part of the environment, so altering the string changes the environment.

我相信在 Win32 上它被称为 _putenv。

见 SetEnvironmentVariable如果你喜欢又长又丑的函数名。
