Macintosh-specific routines for use with Info-ZIP's UnZip 5.1 and later.
|
|
|
|
This source file incorporates the contents of what was formerly macfile.c,
|
|
which supported commands (such as mkdir()) not available directly on the
|
|
Mac, and which also determined whether HFS (Hierarchical File System) or
|
|
MFS (Macintosh File System) was in use.
|
|
|
|
Contains: do_wild()
|
|
mapattr()
|
|
mapname()
|
|
checkdir()
|
|
close_outfile()
|
|
version()
|
|
IsHFSDisk()

MacFSTest()
