This port does not implement the concept of separate slots/tokens.

Parameters

[in]	tokenPresent	This parameter is unused by this port.
[in]	pSlotList	Pointer to an array of slot IDs. At this time, only 1 slot is implemented.
[in,out]	pulCount	Length of the slot list pxSlotList. Updated to contain the actual number of slots written to the list.

Returns

CKR_OK if successful. Else, see PKCS #11 specification for more information.
