io_buf Union Reference

#include <file_io.h>

Public Attributes
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. The u32 and u64 members must only be access through this union to avoid strict aliasing violations. Taking a pointer of u8 should be fine as long as uint8_t maps to unsigned char which can alias anything.
