linux command line in a c file

Question

I'm writing a c-file in linux and I need to put 2 commands in my code but I don't know how to do this.

The commands are

sudo hciconfig hci0 piscan

and

sudo hciconfig hci0 noscan

Thanks in advance

Answer 1

use

system("sudo hciconfig hci0 piscan");

or

FILE *pipe;
pipe=popen("sudo hciconfig hci0 piscan", "r");

to get the output of your command from the pipe, you can use the functions fgets, fread, ... you can read from the pipe like you read from a file
