c++ - How to get the original file extension after INFLATE? -


i'm using zlib , c++ compress/decompress files.

i can deflate file , put .z extension. when inflating .z file have manually put needed extension. inflating works should , can inflate .z file stdout or file.

i 've read zlib manual couldn't manage, how solve problem. suppose need dig archive's header information?

any appreciated, thanks!

the zlib library compress , decompress both zlib , gzip streams. zlib streams have compact header , trailer no provision store file name information. gzip header , trailer on other hand can store file name, can used when decompressing. should read zlib documentation see how use gzip format, , how process gzip header.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
