I am just starting Objective-C, but have other programming experience
(predominantly Java and Visual Basic). I am trying to get socket
programming to work but am having some problems with type
declarations. I am guessing there are some header files I am not
properly importing?
For example I have this:
TCPServer = CFSocketCreate(kCFAllocatorDefault, PF_INET, SOCK_STREAM,
IPPROTO_TCP, kCFSocketAcceptCallBack, (CFSocketCallBack)
&AcceptCallback, &CTX);
And I am getting PF_INET, SOCK_STREAM, IPPROTO_TCP listed as
undeclared.
I imported this:
#import <Foundation/Foundation.h>
#import <CoreFoundation/CoreFoundation.h>
Seeing if I was just missing a header file, but to no avail. Nor can
I find any leads on why it is happening. Any ideas? |

For completeness: CFSocketCreate() is plain C and not Objective-C and
is part of Apple's CoreFoundation framework. You can regard it as some
"internal" implementation library that you should not use (unless you
have a good reason to do so). Unfortunately you can already find a
horrible (and in 99% unnecessary) mixture of Obj-C and CF on the
Web...
If you want to stay within Objective-C, please use the classes
NSStream and friends which wrap most TCP/IP (incl. ssh access).
