uint32_t _PHATFILE::f_de_sect

Sector of the directory entry.

For the root directory this value is zero, because the root doesn't have any entry in another directory.

Offset into the sector containing the directory entry.

Referenced by PhatDbgFileInfo(), PhatDirOpen(), and PhatFileOpen().

unsigned int _PHATFILE::f_de_dirty

Directory entry change marker.

Referenced by PhatDbgFileInfo(), PhatFileOpen(), and PhatFileWrite().

uint16_t _PHATFILE::f_pde_clust

First cluster of the parent directory, low word.

Our directory entry is located in this cluster.

Referenced by PhatDbgFileInfo(), PhatDirCreate(), PhatDirOpen(), and PhatFileOpen().

uint16_t _PHATFILE::f_pde_clusthi

First cluster of the parent directory, high word.

Referenced by PhatDbgFileInfo(), PhatDirCreate(), PhatDirOpen(), and PhatFileOpen().
