get_uint16()

static uint16_t get_uint16 ( const void *  cp )

inlinestatic

Read a 16-bit value beginning at cp. Equivalent to *(uint16_t*)(cp), but will not cause segfaults on platforms that forbid unaligned memory access.

Definition at line 42 of file bytes.h.

get_uint32()

static uint32_t get_uint32 ( const void *  cp )

inlinestatic

Read a 32-bit value beginning at cp. Equivalent to *(uint32_t*)(cp), but will not cause segfaults on platforms that forbid unaligned memory access.

get_uint64()

static uint64_t get_uint64 ( const void *  cp )

inlinestatic

Read a 64-bit value beginning at cp. Equivalent to *(uint64_t*)(cp), but will not cause segfaults on platforms that forbid unaligned memory access.

Definition at line 66 of file bytes.h.

Referenced by commit_decode(), and reveal_decode().

get_uint8()

static uint8_t get_uint8 ( const void *  cp )

inlinestatic

set_uint16()

static void set_uint16 ( void *  cp, uint16_t  v  )

inlinestatic

set_uint32()

static void set_uint32 ( void *  cp, uint32_t  v  )

inlinestatic

Set a 32-bit value beginning at cp to v. Equivalent to *(uint32_t*)(cp) = v, but will not cause segfaults on platforms that forbid unaligned memory access.
