How to invoke command line programatically?

Hello,

I want to issue a command line command from c program?

As an example, I want to run a program like mplayer.

How can i do this?

Regards.

Use the system() command in stdlib.h, for example:

Code:

---

system("ls");

---

Thank you.

Is there a way to check if the statement execution is completed?

It appears like system() waits for the called process to finnish. This is from the man page.

Other than that, I don't know. There might exist a more sophisticated method.

It's up to the implementation (and the command interpreter or shell) but system() often waits for the command to finish and returns the exit code from the program invoked.

On Windows, never use system() (crappy and prohibited by MS)
Use Shell apis

Why do you think it's only crappy on Windows?

"Prohibited by MS"?? Huh?

The return value of system() is the return code of the program which was executed. As long as the shell, and program, aren't brain-dead, this should be accurate. If system() returns 0, then the command executed successfully.

Alex31, recommending a non-portable call when a portable one is perfectly sufficient is naive.
