RE: [Help-glpk] Feature request - option to flush output

Hi, Andrew.

By default, IO streams are not regularly flushed; they are buffered in the 
computer until 'enough' IO has been done (or until the stream is closed).

I'm piping glpsol through some Python code and this buffering is creating a 
noticable delay in my processing.  What I'd like is an option that enables 
explicit flushing of glpsol's output.  For example, after each status line is 
printed, you might execute:


(or do "cout << flush" in C++).
