Convert code to linux

[Hyroshima 19]

I was using this mod from the normal goddameit on windows (vs), but when I tried to compile in linux he accused the lack of a windows library: WINSOCK2.H

would it be possible to convert the ping.c code for linux centos and maintain the same functionality?

 

ping.c

#define new DEBUG_NEW

static char THIS_FILE[] = __FILE__;

	DWORD dwCheckSum = 0;
	USHORT* lpWord = (USHORT*)lpBuff;

	}  	
	if(dwSize ==1)

	dwCheckSum = (dwCheckSum >> 16) + (dwCheckSum & 0XFFFF);
	return (USHORT)(~dwCheckSum);
