Orange Pi Zero Stop a running program with C

[Hikmet TEKIN]

Hi everybody,

 

My question is about stop a running program with C. I have written a c code to start program with system() function in orange pi zero. I am starting RTKLIB software, which is STR2STR and when my code starts the software with command str2str -in serial://ttyS1:115200 -out serial:ttyS2:115200, I can stop it with CTRL^C but I want to stop it from my software. When I got a TCP pocket containing a exit status word. It should stop the STR2STR software. I am not very good at linux. How can I do that?

 

Thanks

If you can start it you can stop it. when you start it keep a reference to the PID, then follow this guide
