in thread Overflow of $DBI::rows

Actually these ints should automatically 64 bits on any sane compiler where SQLLONG would be 64 bits, even if the standard doesn't require it. For clarity they should be fixed to size_t where negative values aren't used to signal errors, although I don't think any of them could be at fault here.

    They cannot be size_t for a start because they have to be able to contain negative values. I cannot comment as to what you believe is a sane compiler but ints and long ints on Windows 64 are 32 bits.

[Corion]: Maybe doing a double-fork (daemonizing) can make go that information away, but maybe not
[Corion]: But I think my knowledge of unix/Linux datastructures is several decades out of date, so I don't really know what information it keeps on processes
[oiskuu]: The useful bits that relate to your process can be found under /proc/self. What information are you thinking of? Tty name?
[tye]: I just daemonized and getlogin() still knew who I had been.
[tye]: perhaps loginuid ? Not that I concede that something not being in /proc means it is not useful.
[Corion]: tye: That's really interesting, but maybe it is because getlogin() returns the name, or the uid, so if that user has been replaced by another user with the same uid in the meantime, that's no problem to the system...
