Python script with PutSTDIN and GetSTDOUT test
When I use the function SBProcess::PutSTDIN to put data into process' STDIN,
the entered data then appears when I get the process' STDOUT.
I attached C++ test program which reads a string (x) and then outputs "stdout:
<x>" and a python script that shows that the stdout contains both "stdout: <x>"
and x. The sleep is there to wait for the program to output data.
// C++ program:
#include <iostream>
using namespace std;
int main(int argc, char** argv)
{
string a;
cin >> a;
cout << "stdout: " << a << endl;
return 0;
}
After I run this program with input "test", it should output "stdout: test".
But when I put "test" to the process via PutSTDIN, the GetSTDOUT contains both
"test" and "stdout: test".
Am I doing something wrong?</pre>
