std::string FName = Arch_FixFileName( VirtualName );
MemRawFile* File = new MemRawFile();
File->SetFileName( VirtualName );
File->SetVirtualFileName( VirtualName );
const void* DataPtr = FReader->GetFileData( FName );
uint64 FileSize = FReader->GetFileSize( FName );
File->CreateFromManagedBuffer( DataPtr, FileSize );

}
Check if a speciied ile exists inside this archive mount point:
virtual bool FileExists(
const std::string& VirtualName ) const
{
return
FReader->FileExists(Arch_FixFileName(VirtualName));
}
virtual std::string MapName(
const std::string& VirtualName ) const
{ return VirtualName; }
private:
clPtr<ArchiveReader> FReader;
};
The
ArchiveReader
class takes care of the memory management and returns a ready-to-
use instance of
MemRawFile
.

Decompressing iles from the .zip archives
We have the
Enumerate_ZIP()
function to iterate through individual iles inside a
.zip
archive, and now it is time to extract its contents.
Getting ready
This code uses the same set of
fopen()
-like functions from the previous recipe.
