Hi,

I am trying to use various Kernel32 APIs that signal errors by returning zero
or false, but the reason for the failure has to be obtained by calling GetLastError, I
mapped that API, but always get zero returned. I suspect that some call required
by JNA is calling a windows function that overwrites the lastError. I tried
setting up my own JNI dll that only contained a call to GetLastError, but this
too always returns zero. Has anyone any ideas how I can get this error code? Rgds Kim
