System objects are treated specially by the Qore library as they are not associated with any QoreProgram object. Additionally, system object constructors are not allowed to raise exceptions.

Parameters

self	the QoreObject that the function is being executed on
code	this argument is necessary in order to be able to provide the va_list in the following argument due to the way QoreClass::execSystemConstructor() is called. If not required by the constuctor, this argument can be ignored.
args	a variable-length list of arguments to the system constructor

q_trid_t

typedef unsigned q_trid_t

type for thread resource IDs (unique within a single running qore library process)
