select() ignoring timeval argument

I am new to this thread.

I am using select() in my code.

my code snippet:
---------------------
twait.tv_sec = 0;
twait.tv_usec = THIRTY_MILLISECONDS;

pollfds2_count = select (0, readfds, writefds,exceptfds, &twait);
From one of the support forums i came to know that select() will return immediately even timeval parameter set to "non zero" or non NULL values. Am i correct? (They mentioned a possible bug in windows).

For our application to work correctly select should wait for THIRTY_MILLISECONDS.

How can i ensure that?

How sleep will help?

Please help me.

What have you written into your fds members?
Are you sure there really is nothing ready?

Passing 0 as the first argument to select() is certainly wrong as well. You need to pass it the actual number of fds you are watching (the maximum of the three sets)
