There's a macro tcp_sndbuf(pcb) that you can use to find out the current fill level of the queue. You may also need to pay attention to tcp_sndqueuelen(pcb) which is used to prevent lots of small packets using up lots of resources and so can prevent a tcp_write() from succeeding. Have a look in the source at how these two are used to give an idea of the tests you need to make.
