Get example how to use writre to a zip archive

[guielec42]

Hello,

I'm trying PhyFS, seams really intresting but there is no example how to use write.
Result is a corrupted zip file
It would be great if I can get some help to understand what is wrong.
I'm using 3.3 release.
here is my simple code:
PHYSFS_init("d:\");
PHYSFS_setWriteDir("d:\");

PHYSFS_mount("d:\\testw.zip", "/" , true);       

const char* writedir =  PHYSFS_getWriteDir();
std::cout << writedir << std::endl; // for testing


PHYSFS_File* txtwtest = PHYSFS_openWrite("/txt2.txt");
int test = PHYSFS_writeBytes(txtwtest, "testwr", 5); // return 5 so it did write somewhere
PHYSFS_close(txtwtest);

PHYSFS_unmount("d:\\test.zip");
PHYSFS_deinit();

You can't write to zip files. It (currently) only allows writing to loose files on the actual filesystem.

I confirm, I can write to the local filesystem. Is it a limitation due to zip archive or more global ?

The API allows it, but it's not implemented for anything but the native filesystem. There are questions about how to rewrite a .zip file to make this work cleanly, since you'd have to deal with the existing data, etc.
