How to get if the file is type of JPEG with jpeglib.h

I would like to ask you if there is any way how to get information(bool value) if the file is jpeg.

I solved it in png like this:

bool isPng = !png_sig_cmp(reinterpret_cast<png_const_bytep>(header), 0, number);

I tried to search on the internet and read the documentation of jpeglib, but didn't solve it.

Thank you for your answers.

If you read the first few bytes of the file you should see the JFIF characters in a jpeg. Using jpeglib you can attempt to read the header data and fail on that.
