Class core.Process

Synopsis: Represents an external process that communicates with its parent via anonymous pipes.

  Base classes:
  Methods: Description:


Writing to the stream sends data to the standard input of the external process.
The standard output (and error output) can be accessed by reading data from the stream.
The stream size indicates how many bytes can be read from the child process.
The waitAvail()() method supports an additional timeout parameter (uses select() on Linux and a polling loop on Windows).
