Beginner: Need some help with BSD sockets...

[antonioetayo]

Heres the code:
http://www.pastebin.co.uk/7303

When I try to compile in debian using g++ I get this error:

network_module_server.cpp: In function `int main()':
network_module_server.cpp:54: error: invalid conversion from `int*' to
`
socklen_t*'
network_module_server.cpp:61: error: parse error before `,' token

I have no idea what the heck is going on. I'm following this tutorial
almost to the letter:
http://beej.us/guide/bgnet/output/html/syscalls.html

Check on the accept() section. And yeah, I know theres a lot possibly
unnecessary comments in the code and whatnot but thats my way of
keeping notes while I learn.
PS: If you know of a better tutorial/book on the subject, please
enlighten me.

I think you want comp.unix.programming, comp.os.linux.networking, or
similar. See this FAQ for what is on-topic here:

http://www.parashift.com/c++-faq-lit...t.html#faq-5.9

Alternately, if you can rephrase your question in terms of standard
C++, we may be able to help further.

Cheers! --M

Well since I'm writing in C++ I figured this was the right place to
ask. I'll try in a Unix group then.

Thanks anyway.

try:
socklen_t address_length;
instead of
int address_length;

If i remember correctly, some platforms define socklen_t to be unsigned
rather than your everyday integer.

Yup, thats what the people at unix programming told me. It compiles
perfectly now. Thanks for the input =)
