'GI.Gio.Objects.Subprocess.Subprocess' allows the creation of and interaction with child
processes.

Processes can be communicated with using standard GIO-style APIs (ie:
'GI.Gio.Objects.InputStream.InputStream', 'GI.Gio.Objects.OutputStream.OutputStream').  There are GIO-style APIs to wait for
process termination (ie: cancellable and with an asynchronous
variant).

There is an API to force a process to terminate, as well as a
race-free API for sending UNIX signals to a subprocess.

One major advantage that GIO brings over the core GLib library is
comprehensive API for asynchronous I\/O, such
'GI.Gio.Objects.OutputStream.outputStreamSpliceAsync'.  This makes GSubprocess
significantly more powerful and flexible than equivalent APIs in
some other languages such as the @subprocess.py@
included with Python.  For example, using 'GI.Gio.Objects.Subprocess.Subprocess' one could
create two child processes, reading standard output from the first,
processing it, and writing to the input stream of the second, all
without blocking the main loop.

A powerful 'GI.Gio.Objects.Subprocess.subprocessCommunicate' API is provided similar to the
@communicate()@ method of @subprocess.py@. This enables very easy
interaction with a subprocess that has been opened with pipes.

'GI.Gio.Objects.Subprocess.Subprocess' defaults to tight control over the file descriptors open
in the child process, avoiding dangling-fd issues that are caused by
a simple @/fork()/@\/@/exec()/@.  The only open file descriptors in the
spawned process are ones that were explicitly specified by the
'GI.Gio.Objects.Subprocess.Subprocess' API (unless 'GI.Gio.Flags.SubprocessFlagsInheritFds' was
specified).

'GI.Gio.Objects.Subprocess.Subprocess' will quickly reap all child processes as they exit,
avoiding \"zombie processes\" remaining around for long periods of
time.  'GI.Gio.Objects.Subprocess.subprocessWait' can be used to wait for this to happen,
but it will happen even without the call being explicitly made.

As a matter of principle, 'GI.Gio.Objects.Subprocess.Subprocess' has no API that accepts
shell-style space-separated strings.  It will, however, match the
typical shell behaviour of searching the PATH for executables that do
not contain a directory separator in their name.

'GI.Gio.Objects.Subprocess.Subprocess' attempts to have a very simple API for most uses (ie:
spawning a subprocess with arguments and support for most typical
kinds of input and output redirection).  See @/g_subprocess_new()/@. The
'GI.Gio.Objects.SubprocessLauncher.SubprocessLauncher' API is provided for more complicated cases
(advanced types of redirection, environment variable manipulation,
change of working directory, child setup functions, etc).

A typical use of 'GI.Gio.Objects.Subprocess.Subprocess' will involve calling
@/g_subprocess_new()/@, followed by 'GI.Gio.Objects.Subprocess.subprocessWaitAsync' or
'GI.Gio.Objects.Subprocess.subprocessWait'.  After the process exits, the status can be
checked using functions such as 'GI.Gio.Objects.Subprocess.subprocessGetIfExited' (which
are similar to the familiar WIFEXITED-style POSIX macros).

Communicate with the subprocess until it terminates, and all input
and output has been completed.

If /@stdinBuf@/ is given, the subprocess must have been created with
'GI.Gio.Flags.SubprocessFlagsStdinPipe'.  The given data is fed to the
stdin of the subprocess and the pipe is closed (ie: EOF).

At the same time (as not to cause blocking when dealing with large
amounts of data), if 'GI.Gio.Flags.SubprocessFlagsStdoutPipe' or
'GI.Gio.Flags.SubprocessFlagsStderrPipe' were used, reads from those
streams.  The data that was read is returned in /@stdout@/ and\/or
the /@stderr@/.

If the subprocess was created with 'GI.Gio.Flags.SubprocessFlagsStdoutPipe',
/@stdoutBuf@/ will contain the data read from stdout.  Otherwise, for
subprocesses not created with 'GI.Gio.Flags.SubprocessFlagsStdoutPipe',
/@stdoutBuf@/ will be set to 'Nothing'.  Similar provisions apply to
/@stderrBuf@/ and 'GI.Gio.Flags.SubprocessFlagsStderrPipe'.

As usual, any output variable may be given as 'Nothing' to ignore it.

If you desire the stdout and stderr data to be interleaved, create
the subprocess with 'GI.Gio.Flags.SubprocessFlagsStdoutPipe' and
'GI.Gio.Flags.SubprocessFlagsStderrMerge'.  The merged result will be returned
in /@stdoutBuf@/ and /@stderrBuf@/ will be set to 'Nothing'.

In case of any error (including cancellation), 'False' will be
returned with /@error@/ set.  Some or all of the stdin data may have
been written.  Any stdout or stderr data that has been read will be
discarded. None of the out variables (aside from /@error@/) will have
been set to anything in particular and should not be inspected.

In the case that 'True' is returned, the subprocess has exited and the
exit status inspection APIs (eg: 'GI.Gio.Objects.Subprocess.subprocessGetIfExited',
'GI.Gio.Objects.Subprocess.subprocessGetExitStatus') may be used.

You should not attempt to use any of the subprocess pipes after
starting this function, since they may be left in strange states,
even if the operation was cancelled.  You should especially not
attempt to interact with the pipes while the operation is in progress
(either from another thread or if using the asynchronous version).
