Hummm, I still don't see how that can work.
my_prio=getpriority(PRIO_PROCESS,0);
if (!(cpid=fork())) {
setpriority(PRIO_PROCESS,0,-20);
execvp(...);
}
some_magic();
setpriority(PRIO_PROCESS,cpid,my_prio);
alarm(limit_time);
So here I have the cpid, which is the PID of the process. How can I know
when the startup is finished ? What is this some_magic() function you are
proposing ?
One last quiestion: how off-topic are we ? :) ehehehe
