timeGetTime v.s. GetTickCount()

referenced from http://www.gamedev.net/community/forums/topic.asp?topic_id=126327
first, timeGetTime is a win32 function, not a c one.

second, timeGetTime is much more accurate than GetTickCount (1 ms vs 50 ms resolution).

third, GetTickCount takes less time to execute.

fourth, nice use of the $. (stolen from Stoffel)

use GetTickCount if 50 ms resolution is acceptable because it has less overhead, and timeGetTime if you need more precise timing. remember to call timeBeginPeriod and timeEndPeriod to obtain 1 ms resolution on nt.

use VC++ generated DLL files in msys

1. make your DLL file with export symbols project by VC++, you should have AAA.dll and AAA.lib
2. to generate libAAA.a for msys or cygwin to use, you should:
   1. generate AAA.def by pexports.exe in msys
      % pexports.exe AAA.dll > AAA.def
   2. generate libAAA.a by dlltool.exe in msys
      % dlltool.exe -D AAA.dll -d AAA.def -l libAAA.a
3. remember to re-define AAAAPI_EXPORTS as blank which is generated by VC++ in AAA.h as you create the export symbol project.
   #define AAAAPI_EXPORTS __declspec(dllimiport)
--> #define AAAAPI_EXPORTS
   or you will get the link error:
   error LNK2001: unresolved external symbol __imp__FUNC
