This function connects to a card in a reader, resets the card and retrieves the ATR (Answer To
|
|
Reset). Based on the ATR, it tries to auto-detect which card driver to use.

If OpenSC was able to connect to the card, a pointer to the sc_card_t object is stored in the
|
|
location pointer to by the <emphasis>card</emphasis> parameter. The card handle should be
|
|
released with <link linkend="scdisconnectcard">sc_disconnect_card</link> when no longer in use.
