推荐答案

命令uname()可以做到.

手册页uname(2)

The command uname() should do it.

manpage uname(2)

您可以从环境变量中获取此版本信息.
您可以对所选择的环境变量使用getenv()函数.
我不确定哪个变量可以在Red Hat上为您提供此信息，但是您可以通过发出env或set命令来检查它.

You could get this version information from the environment variables.
You can use the getenv() function to the environment variable of you choice.
I''m not sure which variable gives you this information on Red Hat, but you could check that by issuing the env or set commands.
