cpio

cpio(4) 						     Kernel Interfaces Manual							   cpio(4)

NAME

       cpio - Format of cpio archive

DESCRIPTION

       The header structure, when the -c option of cpio(1) is not used, is: struct {
		  short   h_magic,
			  h_dev;
		  ushort  h_ino,
			  h_mode,
			  h_uid,
			  h_gid;
		  short   h_nlink,
			  h_rdev
			  h_mtime[2],
			  h_namesize,
			  h_filesize[2]'
		  char	   h_name[h_namesize  rounded  to  word];  }  Hdr;  When  the  -c  option is used, the header information is described by:
       sscanf(Chdr,"%6o%6o%6o%6o%6o%6o%6o%6o%11lo%6o%11lo%s",
	 &Hdr.h_magic, &Hdr.h_dev, &Hdr.h_ino, &Hdr.h_mode,
	 &Hdr.h_uid, &Hdr.h_gid, &Hdr.h_nlink, &Hdr.h_rdev,
	 &Longtime, &Hdr.h_namesize,&Longfile,Hdr.h_name); The Longtime and Longfile are equivalent to	Hdr.h_mtime  and  Hdr.h_filesize,  respec-
       tively.	The contents of each file are recorded in an element of the array of varying length structures, archive, together with other items
       describing the file.  Every instance of h_magic contains the constant 070707 (octal).   The  items  h_dev  through  h_mtime  have  meanings
       explained in stat(2).  The length of the null-terminated path name h_name, including the null byte, is given by h_namesize.

       The  last  record of the archive always contains the name TRAILER!!!  Special files, directories, and the trailer are recorded with h_file-
       size equal to zero.
