The buf argument is a pointer to a stat structure as defined by <sys/stat.h> and into which information is placed concerning the file.  When the macro
     _DARWIN_FEATURE_64_BIT_INODE is not defined (see below for more information about this macro), the stat structure is defined as:

     struct stat { /* when _DARWIN_FEATURE_64_BIT_INODE is NOT defined */
         dev_t    st_dev;    /* device inode resides on */
         ino_t    st_ino;    /* inode's number */
         mode_t   st_mode;   /* inode protection mode */
         nlink_t  st_nlink;  /* number of hard links to the file */
         uid_t    st_uid;    /* user-id of owner */
         gid_t    st_gid;    /* group-id of owner */
         dev_t    st_rdev;   /* device type, for special file inode */
         struct timespec st_atimespec;  /* time of last access */
         struct timespec st_mtimespec;  /* time of last data modification */
         struct timespec st_ctimespec;  /* time of last file status change */
         off_t    st_size;   /* file size, in bytes */
         quad_t   st_blocks; /* blocks allocated for file */
         u_long   st_blksize;/* optimal file sys I/O ops blocksize */
         u_long   st_flags;  /* user defined flags for file */
         u_long   st_gen;    /* file generation number */
     };
