推荐答案

听起来像 system（） 函数：

Sounds like a trivial use-case for the system() function:

system("asterisk -rx reload");

如果您需要对子进程进行非常细粒度的控制，则有更好的方法，但这很简单

If you need very fine-grained control of the child process there are better ways, but this is simple to get going.

此调用启动一个shell（例如bash）来运行命令，这就是为什么我删除了 reload ;它们对于一个单词来说毫无意义，反正会被外壳删除，而且无论如何都不会被启动程序看到。

This call starts a shell (such as bash) to run the command, which is why I removed the quotes around reload; they're pointless for a single word and will be removed by the shell and never seen by the started program, anyway.
