i use popen to get the output of this command:
tail -f /var/log/kern.log
I use a while loop and fgets (to get the output)
the process is running and will not stop. other process cannot run and others hang!
how to solve this?

while( !feof( filePointer ) )
fgets(buff, 500, filePointer);
...Should work.
else you could do:
while(fgets(buff, 500, filePointer) != NULL)
//do something
..or simply:
while(fgets(buff, 500, filePointer) )
if that still doesn't work, be sure (A) the file is a text file, and (B) you opened it in text mode, ie: "r".
