Short question: how can I grab the stdout written to by
C(++), i.e.
C code:
fwrite(...);
std.cstream will be replaced sooner or later.
I don't think I understand the question. stdout is the same
file handle, doesn't matter whether that's using c++'s cout,
c's stdout in stdio.h or D's std.stdio.stdout
writeln("hello world");
is just short for
stdout.writeln("hello world");
also, if you want c io functions, import core.stdc.stdio;
If you're wanting to grab the output from another process,
take a look at std.process
It's a small library written in C++. I can either load it
dynamically or incorporate it into my program. Either way,
when the C++ part does its job, I can see the correct output
in the console window, but I cannot grab it. After analyzing
the C++ code, it seems that it uses fwrite and writes to
stdout.
When I grab stdout I only get the output from the D part, not
from the C++ part.
What do you mean by "grab"?
Redirect it from stdout to somewhere else. If I do something like
this (based on an admittedly old example)
std.c.stdio.freopen("test.txt".ptr, "w+", dout.file);
If I have writeln("Bla");
"Bla" is in the text file. But the string from C++ is not in
there.
