Delphi/Turbo Pascal: AppendWithRetry for text files to retry Append
Posted by jpluimers on 2014/03/10
Every once in a while you have multiple threads or processes wanting to write a short message to the same log file. Append then will give you an I/O error 32 (ERROR_SHARING_VIOLATION), but the below small routine will sleep a bit while retrying a couple of times.
It uses these Delphi aspects around the $I or $IOCHECKS compiler directive:
- in $I+ mode, you get exceptions when certain “classic” Pascal style I/O operations fail.
- in $I- mode, you access the IOResult to obtain the results of those I/O operations
- IOResult gets the result of the last failed operation (if any) or zero if none failed
- IOResult clears the underlying storage to zero
- $IFOPT checks for a certain state of a compiler flag
- You can store the state of $OPT in a temporary conditional define
Note there are a few tables of codes you can get back through IOResult as basically you can get many GetLastError results in IOResult as well: Read the rest of this entry »

Apple Mouse – some links
Posted by jpluimers on 2014/03/10
Slowly completing my Apple II collection, I wanted to buy an Apple Mouse.
Well, that turns out to be a tad complex, as there are various models that are more or less compatible with some of the Apple computers from the mid 1980s.
- Apple Mouse – Wikipedia, the free encyclopedia.
- View topic – Apple Mice differences? – 68k Macintosh Liberation Army Forums.
- Vintage Hardware for The Apple IIe Apple Mouse | eBay.
- Apple II Mouse Interface Card 670 0030 1983 Works | eBay.
- Vintage Apple Mouse II for IIe with Card | eBay.
Mice aren’t the only problems with old hardware: drives and disks die.
Maybe this is a solution:
