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?
