-
- OS/2-specific routines for use with Info-ZIP's UnZip 5.1 and later.
-
- This file contains the OS/2 versions of the file name/attribute/time/etc
- code. Most or all of the routines which make direct use of OS/2 system
- calls (i.e., the non-lowercase routines) are Kai Uwe Rommel's. The read-
- dir() suite was written by Michael Rendell and ported to OS/2 by Kai Uwe;
- it is in the public domain.
-
- Contains: GetCountryInfo()
- GetFileTime()
- SetPathInfo()
- IsEA()
- SetEAs()
- SizeOfEAs()
- GetLoadPath()
- opendir()
- closedir()
- readdir()
- [ seekdir() ] not used
- [ telldir() ] not used
- free_dircontents()
- getdirent()
- IsFileSystemFAT()
- do_wild()
- mapattr()
- mapname()
- checkdir()
- isfloppy()
- IsFileNameValid()
- map2fat()
- SetLongNameEA()
- close_outfile()
- check_for_newer()

- * There are presently two possibilities in OS/2: the output filesystem is
- * FAT, or it is HPFS. If the former, we need to map to FAT, obviously, but
- * we *also* must map to HPFS and store that version of the name in extended
- * attributes. Either way, we need to map to HPFS, so the main mapname
- * routine does that. In the case that the output file system is FAT, an
- * extra filename-mapping routine is called in checkdir(). While it should
- * be possible to determine the filesystem immediately upon entry to mapname(),
- * it is conceivable that the DOS APPEND utility could be added to OS/2 some-
- * day, allowing a FAT directory to be APPENDed to an HPFS drive/path. There-
- * fore we simply check the filesystem at each path component.
- *
- * Note that when alternative IFS's become available/popular, everything will
- * become immensely more complicated. For example, a Minix filesystem would
- * have limited filename lengths like FAT but no extended attributes in which
- * to store the longer versions of the names. A BSD Unix filesystem would
- * support paths of length 1024 bytes or more, but it is not clear that FAT
- * EAs would allow such long .LONGNAME fields or that OS/2 would properly
- * restore such fields when moving files from FAT to the new filesystem.
