file IO

[Ralph Berger]

Hi there,

are there any known errors in PB's file IO functions ?
I only know the freefile() multithread bug.
Have some problems with files > 2 GB.

Sometimes parts of my data are written to the file header. errClear is zero.
Run it on different PC's ( w95 to w2k ). Same error.

After placing all file IO in a C DLL ( fopen, .. ) everthing works.
That's why i ask for PB errors.

I've never had any problems with any PB file verbs.

When you say files > 2000 Mb, are you trying to load the whole file to a string? If that's the case, check your string creation.

If that's not the problem, what specifically is returning "bad" data?

There are definitely no known problems, even with files of that size.

Are you using Quad integers for all your record/seek code?

Can you send over some code to Tech Support than demonstrates the problem please? Thanks!

JFYI, R&D have advised that FREEFILE is likely to become thread-safe in the next version of the compiler.

I am working with files as large as 9GB with no problems...

Thanks for the reply.
Using PB's file fcts in a seperate DLL the error is gone.

Hi there,

sorry for posting. It's a hardware error not a PB error.
If you're using a AMD CPU with VIA Chipset and
82C686B southbridge you'll get problems. http://www.via.com.tw

Don't be!

We all learn things when problems like this are solved and documented on line. If one of my programs has a problem with files >2gig at a customer site, now I'll know where to start.

Lance,

knowing it's not a PB err there are only 2 qs.
What does JFYI stand for ? Who are R&D ?
Are they Ron & Don the 2 guys with the Las Vegas tiger show ?

JFYI is a variation on FYI, meaning Just For Your Information.

R&D is Research and Development.
