Determine raw file-type

Hi,

Apologies if I missed something but is there an API-function to determine the file-type of the raw-file opened (and unpacked) with LibRaw?

Specifically, I would like to know if the file represented by the unpacked C++ LibRaw-class is a DNG-file. I can obviously check the filename extension but I'm assuming LibRaw does some internal matching of file types. Is that exposed through the API somewhere?

Many thanks!

There are a several variables

There are a several variables/calls that delivers specific information:

1) LibRaw::imgdata.idata.dng_version - 0 for not-DNG, non-zero for DNG files
2) LibRaw::get_decoder_info() call
3) four calls:
int is_fuji_rotated();
int is_sraw();
int is_nikon_sraw();
int is_coolscan_nef();
and protected
virtual int is_phaseone_compressed();
Will return non-zero for some specific cases that might be interesting in processing workflow
