This blkno is in d_secsize sectors. * Added d_bootfile to indicate the default operating system * image to be booted by the blk 0 boot. * Changed d_name and d_type to be char arrays rather than ptrs * so they are part of label. This limits length of info in * /etc/disktab, sorry. */ #ifndef _SYS_DISKTAB_ #define _SYS_DISKTAB_ #include <sys/appleapiopts.h> #ifdef __APPLE_API_OBSOLETE /* * Disk description table, see disktab(5) */ #ifndef KERNEL #define DISKTAB "/etc/disktab" #endif /* !KERNEL */ #define MAXDNMLEN 24 // drive name length #define MAXMPTLEN 16 // mount point length #define MAXFSTLEN 8 // file system type length #define MAXTYPLEN 24 // drive type length #define NBOOTS 2 // # of boot blocks #define MAXBFLEN 24 // bootfile name length #define MAXHNLEN 32 // host name length #define NPART 8 // # of partitions typedef struct partition { int p_base; /* base sector# of partition */ int p_size; /* #sectors in partition */ short p_bsize; /* block size in bytes */ short p_fsize; /* frag size in bytes */ char p_opt; /* 's'pace/'t'ime optimization pref */ short p_cpg; /* cylinders per group */ short p_density; /* bytes per inode density */ char p_minfree; /* minfree (%) */ char p_newfs; /* run newfs during init */ char p_mountpt[MAXMPTLEN];/* mount point */ char p_automnt; /* auto-mount when inserted */ char p_type[MAXFSTLEN];/* file system type */ } partition_t; typedef struct disktab { char d_name[MAXDNMLEN]; /* drive name */ char d_type[MAXTYPLEN]; /* drive type */ int d_secsize; /* sector size in bytes */ int d_ntracks; /* # tracks/cylinder */ int d_nsectors; /* # sectors/track */ int d_ncylinders; /* # cylinders */ int d_rpm; /* revolutions/minute */ short d_front; /* size of front porch (sectors) */ short d_back; /* size of back porch (sectors) */ short d_ngroups; /* number of alt groups */ short d_ag_size; /* alt group size (sectors) */ short d_ag_alts; /* alternate sectors / alt group */ short d_ag_off; /* sector offset to first alternate */ int d_boot0_blkno[NBOOTS]; /* "blk 0" boot locations */ char d_bootfile[MAXBFLEN]; /* default bootfile */ char d_hostname[MAXHNLEN]; /* host name */ char d_rootpartition; /* root partition e.g. 'a' */ char d_rwpartition; /* r/w partition e.g. 'b' */ partition_t d_partitions[NPART]; } disktab_t; #ifndef KERNEL struct disktab *getdiskbyname(), *getdiskbydev(); #endif /* !KERNEL */ #endif /* __APPLE_API_OBSOLETE */ #endif /* _SYS_DISKTAB_ */
