Thanks

Did not use 'wait' yet.
How I understand by now the wait works only for child processes, started background.
Is there any other way to watch completion of any, not related process (at least, a process, owned by the same user?)
I need to start a background process, witch will be waiting... (2 Replies)
Hi
I'm studing the system call. I've written a small program that return the time spent in doing some operations. Now I'd like to write one that return the time spent in user mode of a process.
I'm reading that i should use the tms struct:
clock_t times(struct tms *buf);
struct tms {... (2 Replies)
Hi,
I googled a bit, but could not find the answer to my problem.

wait
wait(1) General Commands Manual wait(1)NAME
wait - await process completion
SYNOPSIS
[pid]
DESCRIPTION
If no argument is specified, waits until all processes (started with of the current shell have completed, and reports on abnormal termina-
tions. If a numeric argument pid is given and is the process ID of a background process, waits until that process has completed. Other-
wise, if pid is not a background process, exits without waiting for any processes to complete.
Because the system call must be executed in the parent process, the shell itself executes without creating a new process (see wait(2)).
Command-Line Arguments
supports the following command line arguments:
The unsigned decimal integer process
ID of a command, whose termination is to wait for.
WARNINGS
Some processes in a 2-or-more-stage pipeline may not be children of the shell, and thus cannot be waited for.
