Hi
Attached patch adds the power management header "pm.h" based on
information from: http://msdn.microsoft.com/en-us/library/aa909892.aspx
All these functions are in coredll
...but the patch has two issues (one show stopper).
1. issue (the show stopper) :
The function SetSystemPowerState is declared in winbase.h which is
correct for win32 systems but not for wince, so I moved the wince
declaration to pm.h and added a "#if (_WIN32_WINNT >= 0x0400)" guard to
winbase.h. Now the problem is that the guard in winbase.h does not work
with arm-mingw32ce-gcc and I get:
error: conflicting types for 'SetSystemPowerState'
As far as I can tell _WIN32_WINNT is not defined anywhere with
arm-mingw32ce-gcc
arm-mingw32ce-gcc -dM -E - < /dev/null |grep WINNT
#define __WINNT 1
#define __WINNT__ 1
#define WINNT 1
so why is the _WIN32_WINNT guard not working? I am missing something?
2. issue (non show stopper):
pm.h are missing some defines e.g POWER_NAME, POWER_FORCE and
POWER_STATE_XYZ but I do not know the correct values and I cannot find
them on MSDN. If anyone can pitch in on the missing definions that would
be very good.
Thanks
Lars Munch
