wxProcess

Implements methods from the following classes

• wxEvtHandler

Methods

• wxProcess
  Constructs a process object.
• CloseOutput
  Closes the output stream (the one connected to the stdin of the child process).
• Detach
  Detaches this event handler from the parent specified in the constructor (see wxEvtHandler::Unlink() for a similar but not identic function).
• GetErrorStream
  Returns an input stream which corresponds to the standard error output (stderr) of the child process.
• GetInputStream
  It returns an input stream corresponding to the standard output stream of the subprocess.
• GetOutputStream
  It returns an output stream corresponding to the input stream of the subprocess.
• GetPid
  Returns the process ID of the process launched by Open() or set by wxExecute() (if you passed this wxProcess as argument).
• IsErrorAvailable
  Returns true if there is data to be read on the child process standard error stream.
• IsInputAvailable
  Returns true if there is data to be read on the child process standard output stream.
• IsInputOpened
  Returns true if the child process standard output stream is opened.
• OnTerminate
  It is called when the process with the pid pid finishes.
• Redirect
  Turns on redirection.

Static Methods

• Exists
  Returns true if the given process exists in the system.
• Kill
  Send the specified signal to the given process.
• Open
  This static method replaces the standard popen() function: it launches the process specified by the cmd parameter and returns the wxProcess object which can be used to retrieve the streams connected to the standard input, output and error output of the child process.

wxProcess

wxProcess ( wxEvtHandler &$parent=NULL, integer $id=-1 )

Constructs a process object.
wxProcess ( integer $flags )

Creates an object without any associated parent (and hence no id neither) but allows to specify the flags which can have the value of wxPROCESS_DEFAULT or wxPROCESS_REDIRECT.

CloseOutput

CloseOutput ( )

Closes the output stream (the one connected to the stdin of the child process).

Detach

Detach ( )

Detaches this event handler from the parent specified in the constructor (see wxEvtHandler::Unlink() for a similar but not identic function).

Exists

static bool Exists ( integer $pid )

Returns true if the given process exists in the system.

GetErrorStream

wxInputStream& GetErrorStream ( )

Returns an input stream which corresponds to the standard error output (stderr) of the child process.

GetInputStream

wxInputStream& GetInputStream ( )

It returns an input stream corresponding to the standard output stream of the subprocess.

GetOutputStream

wxOutputStream& GetOutputStream ( )

It returns an output stream corresponding to the input stream of the subprocess.

GetPid

integer GetPid ( )

Returns the process ID of the process launched by Open() or set by wxExecute() (if you passed this wxProcess as argument).

IsErrorAvailable

bool IsErrorAvailable ( )

Returns true if there is data to be read on the child process standard error stream.

IsInputAvailable

bool IsInputAvailable ( )

Returns true if there is data to be read on the child process standard output stream.

IsInputOpened

bool IsInputOpened ( )

Returns true if the child process standard output stream is opened.

Kill

static wxKillError Kill ( integer $pid, wxSignal $sig=wxSIGTERM, integer $flags=wxKILL_NOCHILDREN )

Send the specified signal to the given process.

OnTerminate

OnTerminate ( integer $pid, integer $status )

It is called when the process with the pid pid finishes.

Open

static wxProcess& Open ( string $cmd, integer $flags=wxEXEC_ASYNC )

This static method replaces the standard popen() function: it launches the process specified by the cmd parameter and returns the wxProcess object which can be used to retrieve the streams connected to the standard input, output and error output of the child process.

Redirect

Redirect ( )

Turns on redirection.
