About LinkBacksi 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?
This is a discussion on how to get the output of a non-stop process? within the C Programming forums, part of the General Programming Boards category; i use popen to get the output of this command: tail -f /var/log/kern.log I use a while loop and fgets ...

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".
Code:int main(void){srand(time(0));for(double l=rand(),l0=0,l00=0;;l0+=0.1){for(double l000=0;l000 <1;l000+=.001,l+=((double)rand()/RAND_MAX)/0x64,l00+=((sin(l*0x8*atan(l0)*l000-(l0*0x8*atan (l)))*0.5)+0.5)){l00-=floor(l00);for(size_t l0000=0,l00000=(size_t)(0x50*(l00));l0000<l00000;++l0000 )putchar(0x20);putchar(0x61+(int)((double)rand()/RAND_MAX*0x1a));putchar('\n');}}return 0;}
