Detailed Description

Structure of a directory entry.

Once created, this structure will never change if it points to another directory. Except if the entry is removed.

Field Documentation

uint8_t _PHATDIRENT::dent_name[11]

File name, padded with blanks.

Referenced by PhatDbgDirEntry(), PhatDirCreate(), PhatDirRemove(), and PhatFileOpen().

uint8_t _PHATDIRENT::dent_attr

File attributes.

See PHAT_FATTR_ flags.

Referenced by PhatDbgDirEntry(), PhatDirEntryCreate(), PhatDirEntryFind(), PhatDirEntryStatus(), PhatDirOpen(), PhatDirRead(), PhatDirReleaseChain(), PhatDirRemove(), PhatFileOpen(), PhatFilePosSet(), PhatFileRead(), and PhatFileWrite().

uint8_t _PHATDIRENT::dent_rsvdnt

Reserved byte, possibly used by NT.

Referenced by PhatDbgDirEntry(), and PhatFileOpen().

uint8_t _PHATDIRENT::dent_ctsecs

Hundredth of seconds of file creation time.

Referenced by PhatDbgDirEntry(), and PhatFileOpen().

uint16_t _PHATDIRENT::dent_ctime

File creation time.

Referenced by PhatDbgDirEntry(), PhatDirEntryCreate(), and PhatFileOpen().

uint16_t _PHATDIRENT::dent_cdate

File creation date.

Referenced by PhatDbgDirEntry(), PhatDirEntryCreate(), and PhatFileOpen().

uint16_t _PHATDIRENT::dent_adate

Last file access date.

Referenced by PhatDbgDirEntry(), PhatDirEntryCreate(), and PhatFileWrite().

uint16_t _PHATDIRENT::dent_clusthi

High bytes of first cluster of this file.

If used with the double dot entry, dent_clusthi and dent_clust must be zero if the entry points to the root directory.

The same is true when pointing to a normal file with zero length.

Referenced by PhatDbgDirEntry(), PhatDirCreate(), PhatDirOpen(), PhatDirReleaseChain(), PhatFileOpen(), and PhatFilePosRewind().

uint16_t _PHATDIRENT::dent_mtime

Last file modification time.

Referenced by PhatDbgDirEntry(), PhatDirEntryCreate(), PhatDirEntryStatus(), and PhatFileWrite().

uint16_t _PHATDIRENT::dent_mdate

Last file modification date.

Referenced by PhatDbgDirEntry(), PhatDirEntryCreate(), PhatDirEntryStatus(), and PhatFileWrite().

uint16_t _PHATDIRENT::dent_clust

First cluster used.

This is zero for empty files.

Referenced by PhatDbgDirEntry(), PhatDirCreate(), PhatDirOpen(), PhatDirReleaseChain(), PhatFileOpen(), and PhatFilePosRewind().

uint32_t _PHATDIRENT::dent_fsize

Size of the file in bytes.

For directories, this is always zero.

Referenced by PhatDbgDirEntry(), PhatDirEntryStatus(), PhatFileOpen(), PhatFilePosSet(), PhatFileRead(), and PhatFileWrite().
