I am dizzy!

is not it:

#ifdef _win32

#include

#include

#pragma comment (Lib, "WS2_32.LIB")

INT getselFiplist (unsigned long ipbuff [], int bufcount) {

INT i, count = 0;

Char Hostname [128];

Struct hostent * inaddrs;

IF (getHostName (Hostname, 128) == 0)

{

INADDRS = gethostByName (Hostname);

IF (inadDRS)

{

Count = INADDRS-> H_LENGTH / SIZEOF (IN_ADDR);

IF (count> bufcount) count = bufcount;

For (i = 0; i

{

IPBUF [i] = * (unsigned long *) INADDRS-> h_addr_list [i];

}

}

}

Return count;

}

#ELSE

#include

#include

#include

#include

#include

#include

#include

Int getselFiplist (unsigned long ipbuff [], int bufcount)

{

INT i, count = 0;

Int Sock;

Struct SockAddr_in sin;

Struct ifReq IFR;

SOCK = Socket (AF_INET, SOCK_DGRAM, 0);

IF (SOCK> = 0) //! <0

{

IF (BUFCOUNT> 100) bufcount = 100;

For (i = 0; i

{

Sprintf (ifr.ifr_name, "eth% d", i);

IF (IOCK, Siocgifaddr, & IFR) <0) Break;

:: Memcpy (& SiN, & IFr.IFR_ADDR, SIZEOF (SIN));

IPBUF [count ] = sin.sin_addr.s_addr;

}

Close (SOCK);

}

Return count;

}

#ENDIF

In addition to the function interface specification, others have almost the same, from the code, there is no university!

Perfect

This is the difference between this two functions ...

Perfect waste:

If the function is encapsulated in Windows to .DLL in the Linux package to provide a join interface to provide a join interface to become a common function? :-)
