The GetIpForwardTable function retrieves the IP routing table.
DWORD GetIpForwardTable( PMIB_IPFORWARDTABLE pIpForwardTable, // buffer for routing table PULONG pdwSize, // size of buffer BOOL bOrder // sort the table );
On output, if the buffer is not large enough to hold the returned routing table, the function sets this parameter equal to the required buffer size.
If the function succeeds, the return value is NO_ERROR.
If the function fails, use FormatMessage to obtain the message string for the returned error.
