Programming

Thanks for the help guys.

bcopy() doesn't show up as a usable method - I did find a reference to memcpy, but I get an invalid void 1st parameter error. Any idea what to try? I made sure I had #include <strings.h>

bcopy works like bcopy(source, dest, length);
memcpy works like memcpy(dest, source, length);

So you have to swap the first two. Otherwise they're equivalent. I considered replacing that for you but decided I shouldn't mess with the original code too much. Sorry.

"invalid void first parameter" is a new one on me. functions like memcpy and bcopy usually take void * so you can feed them any kind of pointer without the compiler whining. I suspect something else is wrong, maybe it doesn't like how I'm using the structure members. Can you print the exact line you have and the exact error you get?

[edit] It's string.h, not strings.h. That might do it.

Sure it's:
Going to try switching the params now.

edit: Got the same error. Here's my line of code:

Code:

memcpy(&sa_in.sin_addr, hostentry->h_addrtype, hostentry->h_length);

You forgot to give me the entire line that caused the error, too. None of that should have made it think it was an int, that's odd.

A little bit fell off somewhere or other.

Code:

memcpy(&serv_addr.sin_addr.s_addr, hostentry->h_addr, hostentry->h_length);

Well, now I'm getting errors like:
But I can clearly see (on my windows box) that sa_in.sin_addr.S_un.S_addr exists. Here's my new line of code:

Code:

memcpy(&sa_in.sin_addr.S_un.S_addr, hostentry->h_addrtype, hostentry->h_length);

Ok I tried:

Code:

memcpy(&sa_in.sin_addr.s_addr, hostentry->h_addrtype, hostentry->h_length);

and now I get:

again. On my windows box, s_addr shows up as 364431568

heyooo, I think it worked this time. I tried h_addr instead of h_addrtype like you suggested, and it took. I get this now, but I don't think it's anything to be concerned about?

Never use Windows documentation to program an AIX system! When I said it only vaguely adhered to the standard, I wasn't kidding. It's a bit skewed compared to what you get on a UNIX system.

Do you still have it as strings.h instead of string.h? That might cause that.

Those were included before I started changing anything - if this works (I pray it does) I plan on going back and doing a bit of cleanup in this file. Hard to tell how old it is. I'll let you know how the results turn out (should know in the next hour or so)!
