I am trying to use GetExtendedTcpTable function, but when I want to compile this program:

#include <Windows.h>
#include <Iprtrmib.h>
#include <Iphlpapi.h>

void main() {
    PVOID x = (PVOID)malloc(10000);
    PDWORD size = 10000;
    DWORD result = GetExtendedTcpTable(
        &x,
        &size,
        TRUE,
        AF_INET,
        TCP_TABLE_OWNER_PID_ALL,
        NULL);
}

linker throws an error

LNK2019 unresolved external symbol _GetExtendedTcpTable@24 referenced in function _main

Why is this error, why I cant use GetExtendedTcptable?

Try defining `Tcpmib.h` before `Iphlpapi.h`. Should be automatically `include`d though.... – Fiddling Bits Jan 29 '16 at 16:39

@FiddlingBits This is a linker error. Solution is to pass the appropriate .lib to the linker. Consulting the documentation will tell us the name of that .lib. I'm guessing it is `Iphlpapi.lib`. – David Heffernan Jan 29 '16 at 16:42
@DavidHeffernan You're right. – Fiddling Bits Jan 29 '16 at 16:43
