problem in checking status process PID in c.

Question

I wrote a small program in C.

 

But when i compile it on my pc it goes to " loop" and my pc crashed.

 

program :

 

#include <stdlib.h>

int main()

{

label:;

system("start sleep.exe ");

goto label;

return 0;

}

Solution required:

1) Check sleep.exe is runing or not in process task list of win7.

2)if not running then run sleep.exe.

3)else goto label: for further checking.

program may be something like this:

#include <stdlib.h>

int main()

{

label:;

IF process sleep.exe is runing then{goto label:}

system("start sleep.exe ");

goto label;

return 0;

}

Sir, Here i need some perameter in C which can check whether my exe file(http server) running or not and with its feedback,if not ruuning then it will agian start my exe file(http server). Do you know any command in C like DOS which can check and restart exe when it is stop.??

 

see this one here in DOS we can check process is runing or not if ruuing then error=0 so it will jump to line loop(last line) and if not ruuing then it will jump to next line run that exe then agin go to loop(1st line) for further checking.

 

:loop

tasklist /FI "IMAGENAME eq httpserver.exe" 2>NUL | find /I /V "httpserver.exe">NUL

if "%ERRORLEVEL%"=="0" goto loop

httpserver.exe hostipaddress command

goto loop

 

Thank you

(I WANT TO DO THIS IN C Sir CAN YOU??)
