I don't know if this is a gcc 3 question or a Macintosh question:
On other unixes, with gcc 2.9x, I've used code like the following to
open a compressed file and read it as a C++ istream:
FILE *file = popen("gunzip -c " + name, "r"); // 'name' is a string
ifstream *stream = new ifstream(fileno(file));
This doesn't work with gcc 3.1/OS X 10.2 because ifstream::ifstream(int)
doesn't exist anymore. What's the modern way of doing this? A web search
turned up references to procbuf, a gcc extension class derived from streambuf
for reading from pipes, but I can't find any header files referring to it
on my 10.2 system.
Thanks for any advice. I'm sure I'm missing or forgetting something obvious.
