    Know the output of a command in console

    Hi all.

    How can i obtain the pid of a process, by using a function?

    Like, i know if i write x = system("pidof teste"), x is not the pid of the program teste but it is equal to 0.

    How can i know the output of a command like that, but make it in a a program in C?

    Thanks

    In C, the system() command only returns the status (success or error code). You could look at the popen command or simply redirect the stdout for your command to a file and then read that file in your program.
