The important features + * are: + * \li portability: currently supported platforms are GNU/Linux, FreeBSD, + * NetBSD, OpenBSD, BSD/OS, BeOS, Windows 95/98, Windows NT/2000, MacOS X, + * Solaris, HP-UX and OS/2. + * \li adaptability: unlike most similar projects, libdvdcss doesn't require + * the region of your drive to be set and will try its best to read from + * the disc even in the case of a region mismatch. + * \li simplicity: a DVD player can be built around the \e libdvdcss API using + * no more than 4 or 5 library calls. + * + * \e libdvdcss is free software, released under the General Public License. + * This ensures that \e libdvdcss remains free and used only with free + * software. + * + * \section api The libdvdcss API + * + * The complete \e libdvdcss programming interface is documented in the + * dvdcss.h file. + * + * \section env Environment variables + * + * Some environment variables can be used to change the behaviour of + * \e libdvdcss without having to modify the program which uses it. These + * variables are: + * + * \li \b DVDCSS_VERBOSE: sets the verbosity level. + * - \c 0 outputs no messages at all. + * - \c 1 outputs error messages to stderr. + * - \c 2 outputs error messages and debug messages to stderr. + * + * \li \b DVDCSS_METHOD: sets the authentication and decryption method + * that \e libdvdcss will use to read scrambled discs. Can be one + * of \c title, \c key or \c disc. + * - \c key is the default method. \e libdvdcss will use a set of + * calculated player keys to try and get the disc key. This can fail + * if the drive does not recognize any of the player keys. + * - \c disc is a fallback method when \c key has failed. Instead of + * using player keys, \e libdvdcss will crack the disc key using + * a brute force algorithm. This process is CPU intensive and requires + * 64 MB of memory to store temporary data. + * - \c title is the fallback when all other methods have failed. It does + * not rely on a key exchange with the DVD drive, but rather uses a + * crypto attack to guess the title key. On rare cases this may fail + * because there is not enough encrypted data on the disc to perform + * a statistical attack, but in the other hand it is the only way to + * decrypt a DVD stored on a hard disc, or a DVD with the wrong region + * on an RPC2 drive. + * + * \li \b DVDCSS_RAW_DEVICE: specify the raw device to use. + * + */ + +/* + * Preamble + */ +#include "config.h" + +#include <stdio.h> +#include <stdlib.h> +#include <string.h> +#include <sys/types.h> +#include <sys/stat.h> +#include <fcntl.h> + +#ifdef HAVE_UNISTD_H +# include <unistd.h> +#endif + +#include "dvdcss/dvdcss.h" + +#include "common.h" +#include "css.h" +#include "libdvdcss.h" +#include "ioctl.h" +#include "device.h" + +/** + * \brief Symbol for version checks. + * + * The name of this symbol contains the library major number, which makes it + * easy to check which \e libdvdcss development headers are installed on the + * system with tools such as autoconf. + * + * The variable itself contains the exact version number of the library, + * which can be useful for specific feature needs. + */ +char * dvdcss_interface_2 = VERSION; + +/** + * \brief Open a DVD device or directory and return a dvdcss instance. + * + * \param psz_target a string containing the target name, for instance + * "/dev/hdc" or "E:". + * \return a handle to a dvdcss instance or NULL on error. + * + * Initialize the \e libdvdcss library and open the requested DVD device or + * directory. \e libdvdcss checks whether ioctls can be performed on the disc, + * and when possible, the disc key is retrieved. + * + * dvdcss_open() returns a handle to be used for all subsequent \e libdvdcss + * calls.
