I am trying to call the sleep function with '&' in order to run it in thebackground.
The C program is going to replace the Terminal of linux.
The command line in C program (of Linux) has to include an execl command, but it is not working.
The command is:
execl(path, "sleep", "12&");
Path is : "/bin/sleep".
The execl runs properly if I don`t writes '&', but if I put '&' the output is:
"sleep: invalid time interval ‘12&’
Try 'sleep --help' for more information.".
What should I do? thanks, Haim
