Description
This function is used to open and obtain a handle to an ADM-XRC card.
The particular card to open is identified by the Index parameter. The cards in a system are enumerated in a system-dependent order, and the order of enumeratation may vary depending upon the system's bus topology. Applications should not rely upon a particular order of enumeration.
The handle returned in the Card parameter should be used in all further API calls that need to access this card. When access to the card is no longer required, call ADMXRC2_CloseCard to close the handle and free the card.
