Re: What is the most simple way to use svn_stream_t?

Use svn_stream_from_stringbuf(). That will put the contents of the
file into the stringbuf, which you can access after the cat2() call is

NOTE: be very careful of reading file contents into memory. You really
don't want to try and read a 16 gigabyte file this way.
