Hi Ariel,
 
Thanks very much for the PROBLEM-REPORT-FORM!
 
If you can send a tested patch against the current SVN HEAD, I'll
integrate it before ACE 5.6.

Subject: [ace-bugs] Setting the stack size of thread has no effect
underWINCE



ACE VERSION: 5.5

HOST MACHINE and OPERATING SYSTEM:x86 Win2K

TARGET MACHINE and OPERATING SYSTEM, if different from HOST: PPC 2003
- wince 4.2 

COMPILER NAME AND VERSION (AND PATCHLEVEL): vs 2005

CONTENTS OF $ACE_ROOT/ace/config.h: 

#include "ace/config-win32.h"

AREA/CLASS/EXAMPLE AFFECTED: threads

DOES THE PROBLEM AFFECT:

COMPILATION? no

LINKING? no

EXECUTION? yes 

OTHER (please specify)? N/A

SYNOPSIS:

Setting the stack size under WINCE has no effect.

DESCRIPTION:

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.

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.

I think that the motivation behind this was to disable other flags
that WINCE does not accept (it actually accept only those two
parameters).

The solution is to add the other flag to the mask.

REPEAT BY:

n/a

SAMPLE FIX/WORKAROUND:

n/a

Thanks,

Ariel
