Windows C 系统调用，命令中有空格 [英] windows C system call with spaces in command

问题描述

我无法使用名称和参数中的空格进行系统调用.例如:

I cannot make system calls with spaces in the names and parameters. For example:

system("c:\program files\something\example.exe c:\my files\example.txt");

我尝试过以我知道的各种方式逃避，但没有任何效果.我试过了:

I have tried escaping in every way I know how, and NOTHING works. I have tried:

system(""c:\program files\something\example.exe" "c:\my files\example.txt"");

和

system("c:\program^ files\something\example.exe c:\my^ files\example.txt");

都不起作用.我仍然得到 'c:program' is not a recongnised internal or external command

Neither work. I still get 'c:program' is not a recongnised internal or external command

这真的让我发疯...我需要调用和传递包含空格的参数.由于我不会讨论的原因，我不能使用短符号.

This is really driving me mad... I need to call and pass parameters that have spaces in them. I cannot use the short notation for reasons I won't go into.

我试过用 ' 引号代替 " 引号，但仍然不起作用.我试过在整个事物周围加上引号，在空格周围加上引号，但不起作用.

I have tried with ' quotes instead of " quotes, still doesn't work. I have tried putting quotes around the whole thing and quotes around the spaces and that doesn't work.

有人知道如何正确地做吗?

Does anyone know how to do it properly?

推荐答案

好的，通过进入 system() 调用弄清楚了:你需要一个由于它在内部调用 cmd/c yourinput

OK, figured it out by stepping into the system() call: you need an extra set of quotes around the whole thing due the fact that it internally calls cmd /c yourinput

所以这对我有用:

system("""c:\program files\internet explorer\iexplore.exe" "www.stackoverflow.com""");

有点乱，不是吗?
