May somebody knows how to write
IfErrors or something like that for Zipdll plugin.
ZipDLL::extractall "c:\test.zip" "c:\output" when for example you don't have enough space, or haven't got permission, does zipdll have a exit code or some way of checking for errors?
From its <a href="http://nsis.sourceforge.net/ZipDLL_plug-in" rel="nofollow">wiki page</a>:<blockquote>
On Success, the string "success" is on top of the stack, else an error message.</blockquote>
ZipDLL::extractall "c:\test.zip" "c:\output" Pop $0 ;$0 is now "success" or a error message...
