Problems with DeviceIoControl()
Hi all,
Thanks to Wayne and Park, I''ve got something like this
now:
static VALUE file_set_compressed(VALUE self, VALUE
rbBool){
HANDLE h;
BOOL rv;
DWORD dwBytesReturned;
int fn;
USHORT inBuf = COMPRESSION_FORMAT_DEFAULT;
if((rbBool != Qtrue) && (rbBool != Qfalse)){
rb_raise(rb_eTypeError,"Argument must be true or
false");
}
if(rbBool == Qfalse){
inBuf = COMPRESSION_FORMAT_NONE;

ChangeNotify help wanted
Hi all,
I''ve checked in some code to win32-changenotify. Unfortunately, it
doesn''t work right. I need some help. I don''t understand what,
exactly, I''m supposed to pass to ReadDirectoryChangesW() for the 2nd

Some thoughts on win32-changenotify
...G,
FILE_FLAG_BACKUP_SEMANTICS,
NULL
);
if(hDir == INVALID_HANDLE_VALUE) {
rb_raise(cChangeNotifyError,ErrorDescription(GetLastError()));
}
if(!ReadDirectoryChangesW(
hDir,
Buf,
sizeof(Buf),
bWatchSubtree,
dwNotifyFilter,
&dwBytesReturned,
NULL,
NULL
)){
rb_raise(cChangeNotifyError,ErrorDescription(GetLastError()));
}
So, the question is, what exactly should "Buf" be and how do I read a
single record back out of it?
Any takers?
Regards,
Dan
