<div class="moz-cite-prefix">Hi Michel,<br>
<br>
It doesn't appear to be related to that. I added CloseHandle's
and got the same result.<br>
<br>
Here are my updated findings... The following simple program still
causes the same Handle Leaks...<br>
<br>
Important findings:<br>
<br>
<b>1) </b> If SSL_library_init() and SSL_load_error_strings()
are <b>removed</b> (which are the only 2 OpenSSL functions I'm
using).... the handle leaks go away.. <br>
<br>
<b>2)</b> If SSL_library_init() and SSL_load_error_strings()
are <b>kept</b> but the creation of the thread is <b>removed</b>
-- no more handle leaks..<br>
<br>
So the problem is something related to the combination of loading
OpenSSL and creating a thread (even though that thread does
nothing whatsoever related to OpenSSL). Very odd.<br>
<br>
<br>
DWORD __stdcall thread1(LPVOID l)<br>
{<br>
while(1)<br>
{ Sleep(1000); }<br>
}<br>
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow) {<br>
<br>
<br>
<b> SSL_library_init();</b><b> // if these 2 lines removed<br>
</b><b> SSL_load_error_strings(); </b><b>// no more handle
leaks</b><br>
DWORD t1;<br>
<br>
HANDLE h1=CreateThread(0,0,thread1,0,0,&t1); if(h1==0)
{ return 0; } CloseHandle(h1); <b>//if </b><b>SSL_library_init();</b><b>
</b>and <b>SSL_load_error_strings(); </b>are <b>kept </b>but
this line is <b>removed... no more handle leaks</b><br>
<br>
<br>
while(1)<br>
{<br>
Sleep(1000);<br>
}<br>
}<br>
