using system() in c++

MadOnion87 · 13th March 2004, 11:17 PM

i was making a program that starts another program by using

system("abc.exe");

however, when it starts, it will wait till the other program to close then it closes, how do i make it so that it will exit after running abc.exe?

btw its a console program

you want to fork a new process, and in the child, make the system call. Alternatley, fork and replace the call to system with a call to exec.

I'm sure if you searched google with "fork() example" it would tell you.
