I am experimenting with socket programming using the PC/TCP
development kit.  I am using the example of a simple TCP
application in the book UNIX Network Programming by
W. Richard Stevens.  I have two problems
 
 1. When I try to compile the example client on page 286 I get
    an incompatible types error on  the line:
 
    serv_addr.sin_addr.s_addr = inet_addr(SERV_HOST_ADDR);
 
 
    serv_addr is declared to be of type struct sockaddr_in.  I looked
    in the header files and inet_addr is declared to be of type
    function returning in_addr.  I tryed casting the return value to
    u_long which made the compiler choke.  I then droped the s_addr
    off of the left hand side and the compiler(MSC5.1) took it.
 
 2. The code that was produced does not work.  I ran the same code
    with out the changes on a vax under ultrix and it works, so I
    figured my change was not benign.  The client fails when it
    trys to write to the socket using write().  The error that I
    get back is:
 
        bad file number
 
Can you shed some light on what I might be doing wrong?
