Thank you for your answer, it is helpful. Hee S. Chung heesc@netian.com http://www.netian.com/~heesc

Sure, http://www.netlib.org/cephes/ Actually it was needed to make a program for PalmOS. I'm not using CodeWarrior and currently PRC tools doesn't support math.h for double precision floating point. Only single precision version of math.h is present. So I downloaded the source code of PRC and...

Finally I got it. Thanks. Hee S. Chung heesc@netian.com http://www.netian.com/~heesc

Can I get a reliable and accurate source code in C for math.h which doesn't use harware FPU instructions? Thank you so much. Hee S. Chung heesc@netian.com http://www.netian.com/~heesc

Maybe you think the standard C++ library has some problem in multi-threading environment and it is evidently possible. Then what do you think about this test? The idea to lock mutex for every doubtful place, for example, a pseudo code : mutex_lock cout << &quot;my message&quot; mutex_unlock...

Though a file has .dat as extension, .dat is very commonly used, so I don't know .dat and .kys format. But I suggest a internet site which supplies the great file format informations : http://www.wotsit.org/ Thanks. Hee S. Chung heesc@netian.com http://www.netian.com/~heesc

I couldn't get any reply from Windows CE forum for this problem. It was possible to use PalmOS emulator to develop an application for it. And now I want to develop an application for WinCE, but I don't have a hardware with WinCE. So I hope I can get Windows GE emulator but I couldn't find it...

I cannot figure out your exact situation because I think your problem is not simple. But please consider this scenario. You said an element added and signaled by a thread ( I'll call it thread 1 ). And when it is signaled, another thread (I call it thread 2 ) uses the queue. At this time, if...

Hello, Is there a Windows CE emulator like PalmOS emulator? Thank you so much! Hee S. Chung heesc@netian.com http://www.netian.com/~heesc

Then, is there a reason why we learn programming? There are so many great DBMS which are commercially or freely available. Programming is experience. Hee S. Chung heesc@netian.com http://www.netian.com/~heesc

The standard c function printf is not Printf. So I thought you redefined Printf instead of printf. But what is Printf you used? I don't think it is option or system dependent. Then pleast test following things : 1. %u or %lu instead of %f without casting for 'start' and 'finish' printf(...

Then, what is Printf? Is it redefined printf? Try again using 'printf' instead of 'Printf'. I tested your example and it works well for me when printf is used and casting is applied to 'start' and 'finish'. Thanks. Hee S. Chung heesc@netian.com http://www.netian.com/~heesc

Please try : Printf(&quot;\n start= %f finish=%f &quot;,(float)start,(float)finish); Hee S. Chung heesc@netian.com http://www.netian.com/~heesc

Sorry, I mistyped... DMS -----> DBMS Hee S. Chung heesc@netian.com http://www.netian.com/~heesc

If you want to make a DMS, you need to know data structure. B-tree is frequently used for DB systems. Sometimes AVL tree is used with mmap like mSQL. I think the step will be : 1. Fully understand C language. 2. Fully understand linked list. 3. Study tree data structure and select a suitable...
