The $if support was added recently to pscanner.

Afaik Michael always works with trunk fpdoc, but of course the 3.0.2 docs
were generated in march.

Is this with the 3.1.1 fpdoc?

The declaration is
{$if not defined(fs32bit)}off_t= cint64; { used for file sizes
}{$else}off_t= cint;{$endif}
The 64bit is active, IIRC the 32-bit is for use with FPC_USE_LIBC for whenthe
debian oldstable still defined 32-bit as seek (even though even
somewhatrelevant distros already defined 64-bit).
FPC_USE_LIBC for linux and *bsd still is still hardly used afaik.
Maybe we could clean it out. Why the documentation tool picks the $ELSEbranch I
don't know. I grepped, and it didn't seem to find anything in fpdocor (doc/rtl)
makefiles defining it.
Thanks, I'll code defensively.

These sentences came close together while composing the message, so to be clear: I didn't mean cleaning out FPC_USE_LIBC, only the fs32bit define(with only two occurances) ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
