Alexandre,

Short answer: There is no function that will take a file and return
ClamAV's filetype decision.

All the filetyping functions are all marked internal and expect access to
ClamAV's memory objects. There are ways to use them without modifying
libclamav, but they would all have varying levels of hacks involved. I
don't know which path would be best for you to take, but I wish you luck.
