#include <file_io.h>

Data Fields
uint8_t	u8 [IO_BUFFER_SIZE]
uint32_t	u32 [IO_BUFFER_SIZE/sizeof(uint32_t)]
uint64_t	u64 [IO_BUFFER_SIZE/sizeof(uint64_t)]

Detailed Description

is_sparse() accesses the buffer as uint64_t for maximum speed. Use an union to make sure that the buffer is properly aligned.
