os2.c
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()
SetFileTime() (TIMESTAMP only)
stamp_file() (TIMESTAMP only)
Utime2DosDateTime()
SetPathAttrTimes()
SetEAs()
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()
dateformat()
version()
InitNLS()
IsUpperNLS()
ToLowerNLS()
StringLower()
DebugMalloc()

* There are presently two possibilities in OS/2: the output filesystem is

* 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 IFSes 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.
