this program after compiling, and when trying to link gives the following
error;

ClientConnection.obj : error LNK2001: unresolved external symbol
_close_socket
JavaClientConnection.obj : error LNK2001: unresolved external symbol
_close_socket

In a header file[Sfl.h] that i use in hte program have the closest
conneciton with these error messages. as it has declared functin prototypes
as

#ifdef __cplusplus
extern "C" {
#endif

int    close_socket         (sock_t handle);
char  *socket_peeraddr      (sock_t handle);
.
.
.
.
etc..... and finaly

#if (defined (__WINDOWS__))
int    winsock_last_error   (void);
#endif

#ifdef __cplusplus

And my compilation options are;

/nologo /ML /W3 /GX /O2 /D "WIN32" /D "NDEBUG" /D "_CONSOLE" /D "_MBCS"
/Fp"Release/Main.pch" /YX /Fo"Release/" /Fd"Release/" /FD

Can anyone help me , why it seems to fail linking the obj files? i am simply
lost at this point!!!!

thank you very much for any enlightment

Where did the header file come from, and in what
C source file or library are these functions defined?

Add the C source file to you project, or the library
to you linker options, and try again.
