Is used to notify a virtual user, which is in a waiting state as a result of having called the UserWaitFor function. UserSignal is typically called from within a callback function in order to notify a virtual user about a particular event. The function takes a name as parameter to identify an event object to be signaled.
The scope of this function is the virtual user context, which means that virtual users that use the same event object do not interfere with each other.
