+\membersection{wxProcess::CloseOutput}\label{wxprocesscloseoutput}
+
+\func{void}{CloseOutput}{\void}
+
+Closes the output stream (the one connected to the stdin of the child
+process). This function can be used to indicate to the child process that
+there is no more data to be read - usually, a filter program will only
+terminate when the input stream is closed.
+
+\membersection{wxProcess::Detach}\label{wxprocessdetach}
+
+\func{void}{Detach}{\void}
+
+Normally, a wxProcess object is deleted by its parent when it receives the
+notification about the process termination. However, it might happen that the
+parent object is destroyed before the external process is terminated (e.g. a
+window from which this external process was launched is closed by the user)
+and in this case it {\bf should not delete} the wxProcess object, but
+{\bf should call Detach()} instead. After the wxProcess object is detached
+from its parent, no notification events will be sent to the parent and the
+object will delete itself upon reception of the process termination
+notification.
+
+\membersection{wxProcess::GetErrorStream}\label{wxprocessgeterrorstream}
+
+\constfunc{wxInputStream* }{GetErrorStream}{\void}
+
+Returns an input stream which corresponds to the standard error output (stderr)
+of the child process.
+
+\membersection{wxProcess::GetInputStream}\label{wxprocessgetinputstream}
+
+\constfunc{wxInputStream* }{GetInputStream}{\void}
+
+It returns an input stream corresponding to the standard output stream of the
+subprocess. If it is NULL, you have not turned on the redirection.
+See \helpref{wxProcess::Redirect}{wxprocessredirect}.
+
+\membersection{wxProcess::GetOutputStream}\label{wxprocessgetoutputstream}
+
+\constfunc{wxOutputStream* }{GetOutputStream}{\void}
+
+It returns an output stream correspoding to the input stream of the subprocess.
+If it is NULL, you have not turned on the redirection.
+See \helpref{wxProcess::Redirect}{wxprocessredirect}.
+
+\membersection{wxProcess::IsErrorAvailable}\label{wxprocessiserroravailable}
+
+\constfunc{bool}{IsErrorAvailable}{\void}
+
+Returns {\tt true} if there is data to be read on the child process standard
+error stream.

+\helpref{IsInputAvailable}{wxprocessisinputavailable}
+
+\membersection{wxProcess::IsInputAvailable}\label{wxprocessisinputavailable}
+
+\constfunc{bool}{IsInputAvailable}{\void}
+
+Returns {\tt true} if there is data to be read on the child process standard
+output stream. This allows to write simple (and extremely inefficient)
+polling-based code waiting for a better mechanism in future wxWidgets versions.
+
+See the \helpref{exec sample}{sampleexec} for an example of using this
+function.

+\helpref{IsInputOpened}{wxprocessisinputopened}
+
+\membersection{wxProcess::IsInputOpened}\label{wxprocessisinputopened}
+
+\constfunc{bool}{IsInputOpened}{\void}
+
+Returns {\tt true} if the child process standard output stream is opened.
+
+\membersection{wxProcess::Kill}\label{wxprocesskill}
+
+\func{static wxKillError}{Kill}{\param{int}{ pid}, \param{wxSignal}{ signal = wxSIGNONE}}
+
+Send the specified signal to the given process. Possible signal values are:
+
+\begin{verbatim}
+enum wxSignal
+{
+ wxSIGNONE = 0, // verify if the process exists under Unix
+ wxSIGHUP,
+ wxSIGINT,
+ wxSIGQUIT,
+ wxSIGILL,
+ wxSIGTRAP,
+ wxSIGABRT,
+ wxSIGEMT,
+ wxSIGFPE,
+ wxSIGKILL, // forcefully kill, dangerous!
+ wxSIGBUS,
+ wxSIGSEGV,
+ wxSIGSYS,
+ wxSIGPIPE,
+ wxSIGALRM,
+ wxSIGTERM // terminate the process gently
+};
+\end{verbatim}
+
+{\tt wxSIGNONE}, {\tt wxSIGKILL} and {\tt wxSIGTERM} have the same meaning
+under both Unix and Windows but all the other signals are equivalent to
+{\tt wxSIGTERM} under Windows.
+
+Returns the element of {\tt wxKillError} enum:
+
+\begin{verbatim}
+enum wxKillError
+{
+ wxKILL_OK, // no error
+ wxKILL_BAD_SIGNAL, // no such signal
+ wxKILL_ACCESS_DENIED, // permission denied
+ wxKILL_NO_PROCESS, // no such process
+ wxKILL_ERROR // another, unspecified error
+};
