# case. Program arguments are marshalled and then written to the end of a pipe
|
|
# (in controlleripccall) which is later read from and the arguments
|
|
# unmarshalled (in ipcrecv) before the desired function is called normally.
|
|
# The function return values are then marshalled and written into another pipe
|
|
# (again in ipcrecv) when is later read from and unmarshalled (in runnerar)
|
