<p><font color="#000000" size="3" face="Arial">Welcome to PJSECURE, A simple C
style DLL which can be used as the basis for a network copy registration for your
products. The program is freeware, meaning you are free to use it in anyway you like so
long as you do not redistribute the source code with your product.</font></p>
<p><font color="#000000" size="3" face="Arial">Full source code is provided for those
interested. A VC 5 workspace file (pjsecure.dsw is provided for those who want to rebuild
the dll). Also included is a simple demo console application which calls the 2 functions in
the dll.</font></p>

<p class="rh1"><font face="Arial"><em>pszNicAddress</em> The string buffer which will
contain the NIC address upon successful return from the function.</font></p>
<p class="rh1"><font face="Arial"><em>nBufSize</em> The size of pszNicAddress. This
should be set to 13 or greater prior to calling the function.</font></p>
<p class="rh1"><strong><font face="Arial">Remarks</font></strong></p>
<p class="rh1"><font face="Arial">This function retrieves the NIC address of the network
card installed on the client machine. The client is responsible for allocating the buffer
which will contain the NIC address upon return from the function. All NIC addresses are 12
bytes long so before calling the function you should allocate a buffer of at least 13
bytes to hold the address. The function internally calls the the RCP functions
UuidCreate or UuidCreateSequential.
This means that the code is not dependent on any specific network protocol being
installed. The return is TRUE if the function succeeded else FALSE is returned.</font></p>

<p class="rh1"><font face="Arial"><em>pdwSerialNumber</em> A pointer to a DWORD which
upon return from the function will contain the serial number of the "C" drive.</font></p>
<p class="rh1"><strong><font face="Arial">Remarks</font></strong></p>
<p class="rh1"><font face="Arial">The return value from the function is TRUE if the
function succeeded else it is FALSE. The value returned in pdwSerialNumber can be
displayed by typing "VOL" at a command prompt. For security programs this call
could be used as a secondary means to obtaining unique information about a client
computer.<br>
