ZestSC1FreeImage

ZESTSC1_STATUS ZestSC1FreeImage(ZESTSC1_IMAGE Image);

Parameters

Image FPGA configuration image to free.

Return Value

ZESTSC1_SUCCESS Function succeeded

ZESTSC1_ILLEGAL_IMAGE_HANDLE Attempt to use illegal configuration image

handle

Description

ZestSC1FreeImage should be called when a configuration image handle is no longer

needed. It is used to free resources allocated during ZestSC1LoadImage and

ZestSC1RegisterImage functions.

For example:

extern void *Buffer;

extern unsigned long Length;

ZESTSC1_IMAGE Image;

ZESTSC1_HANDLE Handle;

/* Register the FPGA configuration image */

ZestSC1RegisterImage(Buffer, Length, &Image);

/* Other initialization operations here */

/* Open a card with ID of 1 */

ZestSC1OpenCard(1, &Handle);

/* Other execution operations here */

/* Configure the FPGA from the image */

ZestSC1Configure(Handle, Image);

/* Free resources associated with the handle */

ZestSC1FreeImage(Image);
