PARAMETERS
request This parameter determines the precise action to be taken by these functions.
answer This parameter is an output parameter in which values are returned. The meaning of
answer depends on request parameter.
spu This parameter gives the value of the spu for certain requests.
ldom This parameter gives the value of the locality domain for certain requests.
tid This parameter gives the value of the thread id for certain requests.
