- Rename zfstream.cxx (resp. zfstream.hxx) to gzfstream.cxx (resp.
gzfstream.hxx)
This is because these files only deal with the gzip format (RFC 1952),
while zlib can actually read and write two slightly different formats:
this one and the "ZLIB Compressed Data Format" (RFC 1950). Since I am
going to add std::streambuf and std::istream subclasses able to deal
with both formats (and supporting data sources that are general
std::istream instances, not just files), this renaming will make
things a bit clearer, I hope.
- Add new folder simgear/io/iostreams and move the following files to
this folder:
simgear/misc/gzcontainerfile.cxx
simgear/misc/gzcontainerfile.hxx
simgear/misc/gzfstream.cxx
simgear/misc/gzfstream.hxx
simgear/misc/sgstream.cxx
simgear/misc/sgstream.hxx
simgear/misc/sgstream_test.cxx
- Adapt other files accordingly (mainly #includes and CMakeLists.txt
files).
