Process (gb)

This class is used for managing processes launched by the EXEC or SHELL instructions.

As this class is a stream, you can use input/output instructions to read the process standard output or write to its standard input.

To read the process error output, you must use the Error event.

Constanten

Crashed	Constant used by the State property to indicate a crashed process.
Running	Constant used by the State property to indicate a running process.
Signaled	A synonymous for the Crashed constant.
Stopped	Constant used by the State property to indicate a stopped process.

Statische eigenschappen

LastState	Returns the state of the last terminated process.
LastValue	Returns the return value of the last terminated process.

Eigenschappen

Handle	Returns the process identifier (a.k.a "pid") of the process object.
Id	A synonymous for Handle.
Ignore	Return or set if the process is ignored.
State	Returns the current state of the process object:
Value	Returns the value returned by the process when it exited, or the number of the emitted signal if it crashed.

Blocking	Returns or sets if the stream is blocking.
ByteOrder	Returns or sets the byte order used to read or write binary data to the stream.
EndOfFile	This property signals whether the last use of LINE INPUT reached the end of file, instead of reading a full line with an end-of-line character.
EndOfLine	Return or set the newline separator used by this stream.
Eof	Return if a stream reached its end.
IsTerm	Return if a stream is associated with a terminal.
Lines	Returns a virtual object that allows you to enumerate a stream line by line.
NoShare
NullTerminatedString	Return or set if strings are null-terminated when they are serialized.
Tag	Returns or sets the tag associated with the stream.
Term	Return a virtual object that allows to manage the terminal associated with the stream.

Methode

CloseInput	Closes the process input stream.
Kill	Kills the process immediately.
Signal	Sends a user signal to the process.
Wait	Waits for the end of the process, like the WAIT option in SHELL and EXEC instructions.

Begin	Start to buffer data written to the stream, so that everything will be sent when the Send method is called.
Close	Closes the stream.
Drop	Drop the data that has been buffered since the last call to the Begin method.
ReadLine	Read a line of text from the stream, like the LINE INPUT instruction.
Send	Send all the data, in one shot, since the last call to Begin.
Watch	Start or stop watching the stream file descriptor for reading or writing, after it has been opened.

Gebeurtenissen

Error	Raised when there is data to be read on the standard error output of the process.
Kill	Raised when the process has terminated, normally or abnormally.
Read	Raised when there is data to be read from the standard output of the process.
