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".
