public class TarArchiveSparseEntry extends Object implements TarConstants
The C structure for a sparse entry is:
struct posix_header {
struct sparse sp[21]; // TarConstants.SPARSELEN_GNU_SPARSE - offset 0
char isextended; // TarConstants.ISEXTENDEDLEN_GNU_SPARSE - offset 504
};
Whereas, "struct sparse" is:
struct sparse {
char offset[12]; // offset 0
char numbytes[12]; // offset 12
};
