// WMI (Windows Management and Instrumentation) is a big, complex, COM-based
|
|
// API that can be used to perform all sorts of things. Sometimes is the best
|
|
// way to accomplish something under windows but its lack of an approachable
|
|
// C++ interface prevents its use. This collection of functions is a step in
|
|
// that direction.
|
|
// There are two classes; WMIUtil and WMIProcessUtil. The first
|
|
// one contains generic helpers and the second one contains the only
|
|
// functionality that is needed right now which is to use WMI to launch a
|
|
// process.
|
|
// To use any function on this header you must call CoInitialize or
|
|
// CoInitializeEx beforehand.
|
|
