ZestSC1CountCards

ZESTSC1_STATUS ZestSC1CountCards( unsigned long *NumCards,

unsigned long *CardIDs,

unsigned long *SerialNumbers,

ZESTSC1_FPGA_TYPE *FPGATypes);

Parameters

NumCards Pointer to location to receive total number of ZestSC1 cards in

the system.

CardIDs Pointer to buffer to receive list of card IDs in the system. May

be NULL.

SerialNumbers Pointer to buffer to receive list of card serial numbers in the

system. May be NULL.

FPGATypes Pointer to buffer to receive list of FPGA types fitted to cards in

the system. May be NULL.

Return Value

ZESTSC1_SUCCESS Function succeeded

ZESTSC1_INTERNAL_ERROR An unspecified internal error occurred while

communicating with the driver

Description

ZestSC1CountCards can be used to determine the number and types of cards fitted in a

system. Each card can be identified in 3 ways: by a user-programmable card ID, by a

factory set unique serial number and by the type of FPGA fitted to the card.

CardIDs should point to the start of an array which will be filled in with the user

programmable card IDs. See ZestSC1SetCardID for details of how to set this ID. This

ID should be passed to ZestSC1OpenCard to obtain a handle for accessing the selected

ZestSC1 card.

SerialNumbers should point to the start of an array which will be filled in with the factory

set, unique serial number of the cards in the system.

FPGATypes should point to the start of an array which will be filled in with the type of

FPGA fitted.

Each of these arrays should be large enough to receive values for each of the cards in the

system. Any or all of them can be NULL if the information is not required. A call to

ZestSC1CountCards can be made with NULL pointers to determine the size of the

required array as follows:

1 2 ... 23 24 25 26 27 28 29 30 31 32 33 ... 56 57
