stdout to file opened with fopen

[samuel . hartmann]

Hello,

I want the stdout to be written to a file I opened before with fopen. But
it does not work on Octave 2.1.42 under Cygwin.

I tried it as follows:

fid=fopen("outputfile","w");
[newfid,msg]=dup2(fid, stdout);

the dup2 function returns -1 as newfid, msg is empty.

As I remember this worked with Octave 2.0.16 on Linux.
Can anybody help me?

Perhaps someone knows another way for what I want to do: I want to call a
command, which writes the output to a file opened before with fopen.


Thanks,

Samuel
