public class PosixTarEntry extends TarEntry
The C structure for a USTar Entry's header is:
struct posix_header
{
char name[100]; //File name. Null-terminated if room.
char mode[8]; //Permissions as octal string.
char uid[8]; //User ID as octal string.
char gid[8]; //Group ID as octal string.
char size[12]; //File size in bytes as octal string.
char mtime[12]; //Modification time in seconds
// from Jan 1, 1970, as octal string.
char chksum[8]; //Sum of octets in header as octal string.
char typeflag; //An enum ustar_type value.
char linkname[100]; //Name of link target.
// Null-terminated if room.
char magic[6]; //"ustar\0"
char version[2]; //"00"
char uname[32]; //User name, always null-terminated.
char gname[32]; //Group name, always null-terminated.
char devmajor[8]; //Device major number as octal string.
char devminor[8]; //Device minor number as octal string.
char prefix[155]; //Prefix to file name.
// Null-terminated if room.
};
Actually the posix_header structure is the same with an exception of padding -
