I also discussed this with Lev and, despite this being different from
what we do in the *nix world (where decimal representations make sense
for file descriptors), it seems to be the right hting to do on Windows
when using HANDLEs (shrug).
Windows kernel handles are very much "like" fds though the handle table
also covers processes, threads, semaphores etc. They are not pointers,
are generally smallish numbers or ~0 (== -1). But not as small as fds in
the Unix/Linux world --- mainly because several objects share the name
space and they have to be multiples of 4 for some arcane reason.
The problem here was not printing as "decimal" but as "unsigned
decimal". Use of the latter would have caused the same issue on Linux too.
Using hex is a compromise here as handles are defined as "unsigned ints"
of the same size as pointers. So PRIdPTR somehow looks improper though I
would have chosen that.
Given your explanation then it sounds like we should truly use PRIdPTR.
Wouldn't you agree Lev?
Cheers,
Selva
