<P DIR=LTR><SPAN LANG="en-us"><FONT SIZE=2 FACE="Courier New">DESCRIPTION:</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT SIZE=2 FACE="Courier New">The CreateThread function of wince accept stack size as the first argument. But this parameter is ignored unless the flags parameter contains the flag STACK_SIZE_PARAM_IS_A_RESERVATION.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT SIZE=2 FACE="Courier New">The problem is that the call CreateThread in ACE (inside ACE_BEGINTHREADEX) changes the flags like this: (FLAGS) & CREATE_SUSPENDED. And so the stack size has no affect.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT SIZE=2 FACE="Courier New">I think that the motivation behind this was to disable other flags that WINCE does not accept (it actually accept only those two parameters).</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT SIZE=2 FACE="Courier New">The solution is to add the other flag to the mask.</FONT></SPAN></P>
