Mac/Unix 64bit file size/operaion

[nminkov]

I am currently investigating cross platform libraries for Windows/MacOSX applications.
Poco is a very clean library and I like very much like the coding style.

Was checking the source code, it seem that the Unix/Mac implementation of File does not support 64bit file sizes/operations (stat() returns int). Am I missing something or is that really the case. (I think GNU and VC++ have stat64())

On Mac OS X and Linux (with the proper -D_FILE_OFFSET_BITS=64) it is not necessary to explicitely use the 64-bit file functions, as the normal functions (e.g., stat) can handle 64-bit file offsets and lengths as well (e.g., off_t is 64 bit on Mac OS X).
Also, the Poco::FileSize type is 64 bit as well, so there shouldn't be any problems dealing with large files.

The situation might be different with other Unix platforms, though.

Thanks for the quick reply.

Great news the 64 bit works as it's supposed to.

I am really new to cross platform programming and just beggining to discover it's "joys".

Next steps: find IDE and GUI library (real pain)

At least you're starting at the right place :-)

> Next steps: find IDE

Eclipse/CDT may be a good choice, but I could not wean myself from Visual Studio, so I have somewhat exotic approach to non-Windows development - I keep the code on a shared Linux or Solaris drive, edit with VS, use two monitors with [url=http://synergy2.sourceforge.net/|Synergy] and debug with gdb/http://sources.redhat.com/insight/|Insight] or dbx/[http://www.gnu.org/software/ddd/]DDD[/url.

and GUI library (real pain)

Poco::WebWidgets should be released in 1.4 (I hope). If you need thick native GUI, we'd really like to see it in POCO but so far only [url=http://pocoproject.org/poco/wiki/tiki-view_forum_thread.php?comments_parentId=910&topics_offset=4&forumId=3|ideas] have been tossed around. After much research, my favorite wrapping candidate is http://www.tecgraf.puc-rio.br/iup/]IUP[/url.
