_7zCallback

Call a function for each extracted file, with or without error.
Note : the ObjLZMA object is automatically created, you must NOT use lzmaCreate.
Warning : the prototype is only __callback__ and __user_parameter__, no lzma object !

Prototype :

fun [fun [ObjLZMA u0 S S I I I] u1 u0] ObjLZMA

• fun [ObjLZMA u0 S S I I I] u1 : the callback
  
  
  • ObjLZMA : usually not applicable
  • u0 : a user parameter, at your convenience
  • S : the name of the archive (by example, "archive.7z")
  • S : the name of the extracted item
  • I : 0 if the current item is a file, 1 if it is a directory
  • I : the size of the extracted item (0 if it is a directory)
  • I : the state : 0 if the current item extraction is a success, otherwise an error code number.
  
  
• u0 : a user parameter, at your convenience

Return : ObjLZMA usually not applicable.
