<p>Now I finish development of Win64 GUI for a call of the Gromacs commands. <br>
It uses well structured help of Gromacs utilities for dynamic creation of modeless dialog boxes
<br>
for a choice of parameters of a commands and then commands execution. <br>
It is implemented by non-blocked I/O redirection of gmx I/O through named pipes.<o:p></o:p></p>
<p>The main problem which I taked - The commands in interactive mode of user interaction hungs up,
<br>
so without showing anything in the pipes. After some time of dances with tambourines (debugging),<br>
I understood that faults caused by buffering of stdout/stderr, <br>
the problem was solved by adding of fflush (stdout/stderr) before an interactive call of fgets (., stdin).<br>
In this regard I have any questions to developpers: <br>
- whether it makes a sense to add correction to a repository or it is better to make it to authors of a code?<br>
- why such disorder with use of stdout and stderr in sources?<br>
List of files witsh adding fflush:<o:p></o:p></p>
