Not a wrapper, but peculiar to libisoburn.
@param d The drive which holds an existing ISO filesystem
@param read_opts The read options which can be chosen by the application
@param volset the volset that represents the image, or NULL if the image is
empty.
<<<<< What about return a volset without file if image is
empty <<<<<<<<<
@param volset the volset that represents the image, if the disc is blacnk
it will have no files
@return <=0 error , 1 = success
>>>>> error means damaged or unsupported image
error code is stored in ecma119_read_opts in libisofs
