ZestSC1OpenCard

ZESTSC1_STATUS ZestSC1OpenCard( unsigned long CardID,

ZESTSC1_HANDLE *Handle);

Parameters

CardId ID of card to open. See ZestSC1CountCards.

Handle Pointer to receive the handle of the open card. This handle is

used to identify the card in future calls to the ZestSC1 library.

Return Value

ZESTSC1_SUCCESS Function succeeded

ZESTSC1_INTERNAL_ERROR An unspecified internal error occurred while

communicating with the driver

ZESTSC1_OUT_OF_MEMORY Not enough memory to complete the

requested operation

ZESTSC1_ILLEGAL_CARD_ID The requested card ID does not correspond

to any devices in the system

Description

ZestSC1OpenCard is used to obtain a handle to a card in the system for future calls to

ZestSC1 library functions. The card is identified by a user-programmable ID. See

ZestSC1CountCards for details of how to find the IDs of cards in the system and

ZestSC1SetCardID for details of how to set this ID.

For example:

ZESTSC1_HANDLE Handle;

/* Open a card with ID of 1 */

ZestSC1OpenCard(1, &Handle);

/* Configure the FPGA on the open card */

ZestSC1ConfigureFromFile(Handle, “test.bit”);

ZestSC1CloseCard should be called to free the card before the program exits.
