The event parameter container contains the following information:

1. Parameter name. To retrieve the name, use the PrlEvtPrm_GetName function.
2. Parameter data type. Depending on the event type, a parameter can be of any type defined in the PRL_PARAM_FIELD_DATA_TYPE_PTR enumeration. To retrieve the parameter data type, use the PrlEvtPrm_GetType function.
3. Parameter value. Depending on the parameter data type, the value must be retrieved using an appropriate function from the PHT_EVENT_PARAMETER group (see the function list below). For example, a boolean value must be retrieved using the PrlEvtPrm_ToBoolean function, the string value must be retrieved using the PrlEvtPrm_ToString function, if a parameter contains a handle, it must be obtained using the PrlEvtPrm_ToHandle , etc. The meaning of the value is usually different for different event types.
