Fast process invocation.
fast_popen opens a process for execution, providing its output on a stream, just like the standard
popen. However, fast_popen does not invoke the shell to interpret the command, which can be very time consuming. Thus, the command must be given as a full path, and may not include quotes, variables, or other features of the shell. (Note: there is no pipe close, we rely on SIGPIPE to kill the child.)
|command||The command string to execute.|
|in||A pointer to a standard I/O stream, which this function will attach to the standard input of the process.|
|out||A pointer to a standard I/O stream, which this function will attach to the standard input of the child process.|
