error when compiling c++ source code

dilver (142)
When trying to compile a software from a source code using Cygwin , in windows xp , I got this error:

basic_dump.c:99:3: error: ‘VOID’ undeclared (first use in this function)
(VOID)(param);


This is the code that engenders the error :

Any help on how to correct the error would be appreciated

Well, that seems to be some random code randomly put together. What is the purpose of that stuff?

that is a source code of a file called basic_dump.c ,among other files, that should be compiled to get the executable file . I used the cat command of Linux to get its content . However when I try to compile them using the make command , I get the error above and I think it comes from that file .

The entire content is garbage. it cannot be fixed. Here is an article about pcap:

Look at line 39, the printf() function is probably FUBARRED: printf():",i);
