how to use batch in c-CodePudding

I have a batch program that I would like to add to one of my c programs. The batch program tests if a file exists and exits the script if it doesn't. I do not want to add any more libraries to my code. The problem that I have is that I am not sure how I am able to use batch in c . I am able to figure everything else out on my own I just need to know this one thing.

CodePudding user response：

You can use the system(" ") command to use batch.

Assuming you are on Windows, you have two options available to run batch files on Windows from C/C .

You can use system (or _wsystem for wide characters).

"The system function passes command to the command interpreter, which executes the string as an operating-system command. system refers to the COMSPEC and PATH environment variables that locate the command-interpreter file (the file named CMD.EXE in Windows 2000 and later)."

You can use CreateProcess directly.

Note that for batch files:

"To run a batch file, you must start the command interpreter; set lpApplicationName to cmd.exe and set lpCommandLine to the following arguments: /c plus the name of the batch file."
