the code not on the package it's just one file code, i got it from my friend cause he don't know how to use it and he didn't tell me where he got that code and
i don't save that code on my pc

so i just had test that code on my pc friends using borland commandline tools, but from that code need "libnet.h" and
on borland include files there is no "libnet.h", i had checked on my linux yesterday and "libnet.h" is exist. I know maybe that code just for linux system/write on linux
but can i just copy the libnet.h/another header or library files which not exist to my borland include files folder or conversely(well i'm not positive sure about this

),
or in this thing my friend just missing another component from the source code

Thanks a lot.
