The contents of each file are ! 36: recorded in an element of the array of varying lenght ! 37: structures, archive, together with other items describing ! 38: the file. Every instance of h_magic contains the constant ! 39: 070707 (octal). The itimes h_dev through h_mtime have ! 40: meanings explained in stat(2). The length of the null- ! 41: terminated path name H_name, icluding the null byte, is ! 42: given by h_namesize. ! 43: .sp ! 44: The last record of the archive always contains the name ! 45: TRAILER!!!.
