Hi,
I've attached simple cpp program which demonstrates the
problem.
The program works fine from cmd.exe, but fails when started
from cygwin.
The program does the following:
- The main thread creates a helper thread which reads stdin
and prints
the data read.
- stdin is read via ReadFile() Win32 API function.
- At the end of the main function, the main thread calls
CloseHandle()
func for the stdin. It causes the ReadFile() function to
return, and
the helper thread to finish. From cmd the program works as
described.
- Under Cygwin the program works differently. The helper
thread is
not finished, because it doesn't exit from the ReadFile()
func. The
main thread waits for the helper thread's completion during
1 sec,
then it calls TerminateThread() Win32 API func.
When I start the program from cmd, I see the following
output:
>read_stdin_example.exe
Stdin_Reader_Thread has been completed
When I start the program from Cygwin, I see:
$ ./read_stdin_example.exe
Stdin_Reader_Thread has NOT been completed. So, it will be
terminated.
I believe that this information would be enough to
investigate and fix
the problem.
If you need more information or have questions, feel free to
contact me.
Have a nice day!
