izvrsavanje komandi na sistemu (linux), zombi problem

[ u_m @ 29.06.2005. 10:44 ] @

koristim komandu ping koju pozivam sa:

Code:
ping = popen( &komanda[50] ,"r");

i to se vrti u petlji za svaku adresu koju provjeravam.

milan 57485 0.0 0.0 0 0 p0 Z 11:30AM 0:00.03 <defunct>
milan 57487 0.0 0.0 0 0 p0 Z 11:30AM 0:00.02 <defunct>

ovakav po jedan se stvara za svaku ip adresu koju provjeravam

i top prikazuje ovo:

Citat:

50 processes: 2 running, 32 sleeping, 16 zombie

ubacio sam fclose, ali opet isto...

kako da sprecim stvaranje ovakvih zombi procesa?
