+
+ 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()
