/**
* APT_U::ReceiveParameter service function. This returns the current parameter data from NS state,
* from the source process which set the parameters. Once finished, NS will clear a flag in the NS
* state so that this command will return an error if this command is used again if parameters were
* not set again. This is called when the second Initialize event is triggered. It returns a signal
* type indicating why it was triggered.
* Inputs:
* 1 : AppID
* 2 : Parameter buffer size, max size is 0x1000
* Outputs:
* 1 : Result of function, 0 on success, otherwise error code
* 2 : Unknown, for now assume AppID of the process which sent these parameters
* 3 : Unknown, for now assume Signal type
* 4 : Actual parameter buffer size, this is <= to the the input size
* 5 : Value
* 6 : Handle from the source process which set the parameters, likely used for shared memory
* 7 : Size
* 8 : Output parameter buffer ptr
