/*
|
|
* A set of compatibility glue for building libarchive on Windows platforms.
|
|
*
|
|
* Originally created as "libarchive-nonposix.c" by Kees Zeelenberg
|
|
* for the GnuWin32 project, trimmed significantly by Tim Kientzle.
|
|
*
|
|
* Much of the original file was unnecessary for libarchive, because
|
|
* many of the features it emulated were not strictly necessary for
|
|
* libarchive. I hope for this to shrink further as libarchive
|
|
* internals are gradually reworked to sit more naturally on both
|
|
* POSIX and Windows. Any ideas for this are greatly appreciated.
|
|
*
|
|
* The biggest remaining issue is the dev/ino emulation; libarchive
|
|
* has a couple of public APIs that rely on dev/ino uniquely
|
|
* identifying a file. This doesn't match well with Windows. I'm
|
|
* considering alternative APIs.
