Question have an about LibClamAV.dll
Hi Developers,

I've an query about doing the scan using byte[] help of LibClamAV.dll(win32). If anyone know the methods to pass the byte[] provide the details?.

Note:
I able to do the scan a physical path file. But not able to do with byte[]. Please help me.

Regards,
Suresh Shanmugam.

It sounds like you are interacting with libclamav from C#. ClamAV requires a rewindable file stream, so a byte array can’t be scanned on its own.

You could map the byte array to a MemoryMappedFile.

http://stackoverflow.com/questions/10806518/write-string-data-to-memorymappedfile <http://stackoverflow.com/questions/10806518/write-string-data-to-memorymappedfile>

Then you could potentially pass the file descriptor for this to native library.

Hi Brandon Perry,

You are correct Perry. I am implementing the LibClamAV Library into C# application. So I need to get the File descriptor from the Stream and need to assign the value to "cl_scandesc" Native method. Am I right?.

Yes, I believe that’s correct.

Hi Brandon Perry,

Okay. If you don't mind. Do you have any samples of implementation using stream?. If you have please share to me.

Hi Perrry,

I am not able to get the FileDescriptor for stream data because it is expecting always Physical file.
