[C++] popen and ofstream(int) with g++ 3.0
Hi!
I have some trouble with tela. When compiling with g++ 3.0, there is
no ofstream(int) function (as in STL). This gives a problem when
using popen(), as it returns a FILE*, and tela then uses an ofstream
to read from the process. I've used the patch below, but I'd say it's
an ugly hack. What's the suggested way to use popen functionality
with STL?
