I have a question: right now I'm trying to use a commercial version of a dll, compiled by someone I can't contact. How do I know against which version of msvcrt.dll it was compiled? Furthermore, let say for example that it's compiled against the version 2.24 (just a casual number, I have no clue on how msvcrt.dll is versioned) Even if I recompile my GLib/GTK+ on my computer, how can I be sure to use the right version of msvcrt.dll? I could have a completely different version of msvcrt.dll on my PC and I'm back to square one...

[win32]g_iochannel and USB
I'm trying to use a DLL for managing an USB connection. In this DLL there is a function to open the USB channel wioth this prototype: int CP210x_Open(DWORD dwDevice, HANDLE* cyHandle); I thought I could link to that handle an iochannel, but I'm not able to make it work. I wrote and compiled the following code: ---SNIP--- GIOChannel *USB_giochannel; int USB_status; HANDLE USB_handle; DWORD USB_device; USB_device = 1; USB_status = CP210x_Open(USB_device, USB_handle); USB_giochannel = g_io_channel_win32_new_fd((int)USB_handle); --PINS--- but when I run it I get the message: GLib-WARNING **: g_io_channel_win32_new_fd: 1740 isn't an open file descriptor in the C library GLib uses. What am I doing wrong? mingw32-gcc version 3.4.5 GTK+ version 2.24.8 -- Regards, Manuel Ferrero RD department Reer SpA Tel. +39 011 2482215 Fax. +39 011 859867 L'utilizzo non autorizzato del presente messaggio e' vietato e potrebbe costituire reato.
