How to write exceptions or something like that in NSIS with the Zipdll plugin?

Question

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?

Answer 1

From its wiki page:

On Success, the string "success" is on top of the stack, else an error message.

ZipDLL::extractall "c:\test.zip" "c:\output"
Pop $0
;$0 is now "success" or a error message...
