wait for 2 seconds

[munna_dude]

hi all
how can i sleep a command that is popen("xxxxxx","r");
to two seconds.
i wrote my program like this

popen("xxxxxx","r");
sleep(2)
popen("xxxxxx","r");

but it is not waiting for 2 seconds. it is directly excuting.
it have to wait to excute the second popen()
how can i do?, is there any other way to wait for 2 seconds.

please help me

thank you in advance

I'm a little bit confused...

You want to wait 2 seconds before running popen? Then simply remove the first popen.

If you want to run popen and timeout after 2 seconds, the only way I can think of would be starting a separate thread and passing a reference to the FILE* to the starting function. Then use that separate thread to run popen, with a sleep call in the main thread. After sleep returns, you kill the thread if it's not already exited, and then you can check the status of the FILE* you passed in.

There may be a simpler way to do the latter, but I'm not sure what it would be.
