vhl_select

With the help of this function you select a card located in the antenna field. If successful, the
status "OK" is returned.
The type of the selected card is returned in the parameter "CardType".
With the "vhl_select" function you can select the card located in the antenna field of the
reader. When "VHLSelect" is called again, the currently selected card is changed to the "Hold
mode" and "vhl_select" returns the value "NOTAG_ERR".
If you want to select a card again without removing it physically from the antenna field, you
need to set the "Reselect" parameter to "true". If there are several cards in the antenna field
of the reader and you want to select all cards, set the parameter "Reselect = false". Then call
the "vhl_select" function until all cards in the antenna field are recognized. If no new card is
detected, "CARD_NOT_SELECTED_ERR" is returned.
