/**
cxxtools::posix::CommandInput starts a process and the stdin is connected to the current process.
The class is derived from std::ostream. You can use all methods provided
from that class to send data to the stdin of the process.
Typical usage example:
\code
cxxtools::posix::CommandInput grep("grep");
grep.push_back("foo"); // add a parameter
grep.run(); // runs the process
grep << "foo" << std::endl; // this line is printed
grep << "bar" << std::endl; // this line is not printed
grep << "foobar" << std::endl; // this line is printed
\endcode
