Errno may not be reset from a previous value. For example, if you call recv() once, and receive EINTR, errno will remain set to EINTR until some other error occurs.

Therefore, you shouldn't use errno to detect if there's an error or not. You should only check it's value when you know that there's an error, and you want to know what the error is.

Personally, I typically do something like this:

        recvlen = recv( . . . );

        if (recvlen = -1);
            err = errno;
            select;
            when err = EINTR;
                // timeout!
            when err = (other expected error);
                // handle appropriately
            other;
                errMsg = %str(strerror(Errno));
                // show error to user;
            endsl;
        endif;

        // no error -- handle received data.
