int cudbg_read_flash_details	(	void *	handle,
		struct cudbg_flash_hdr *	data
	)

cudbg_read_flash_data - Read cudbg “flash” header from adapter flash. This will be used by the consumer mainly to know the size of the data in flash.

Parameters

@handle : A pointer returned by cudbg_hello. @data : A pointer to data/header buffer
