im developing an extension under Win32 which links to libiconv, but i'm having a slight problem. i have a conversion which fails (iconv returns (size_t)-1), but errno is set to 0. any clues as to what is happening ? not that it matters, but the conversion is from ISO-8859-1 to UTF-16 . l0t3k

That's most likely iconv.dll and your extension are linked to different libc dlls since errno variable is both dll specific and thread specific. It also fails to set a correct value to errno if your iconv.dll is statically linked to MS libc. Moriyoshi

thanks for the quick response. i guess i have some digging to do. by the way, how far along is the new mbstring ? libiconv is not too convenient or smart on chunked conversions (which is where my problem lies) my last look a mbstring made me believe that this is something you consciously address. since my extension is ZE2 specific, i have some time to play with. l0t3k "Moriyoshi Koizumi" <moriyoshi@at.wakwak.com> wrote in message news:20030518101203WUqOgo@at.wakwak.com...

Well, so far I didn't make significant progress in that, unfortunately. I'm still stuck with the API design as I'm still looking for a reasonable settlement between per-character-basis and per-octet-basis. BTW I've got no such idea that iconv is less convenient for chunked conversion. IMO some thin wrapper on the library could help as well as you want. Moriyoshi
