◆ 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.

Referenced by cell_unpack(), fetch_ext_or_command_from_buf(), packed_cell_get_circid(), parse_create2_payload(), peek_buf_has_control0_command(), and relay_header_unpack().

◆ 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.

Definition at line 54 of file bytes.h.

Referenced by cell_unpack(), connected_cell_parse(), get_random_virtual_addr(), and packed_cell_get_circid().

◆ 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.

◆ get_uint8()

static uint8_t get_uint8 ( const void *  cp)
inlinestatic

◆ set_uint16()

static void set_uint16 ( void *  cp,
uint16_t  v 
)
inlinestatic

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

Definition at line 78 of file bytes.h.

Referenced by cell_pack(), connection_write_ext_or_command(), control_send_v0_reject(), relay_header_pack(), and var_cell_pack_header().

◆ 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.

Definition at line 87 of file bytes.h.

Referenced by cell_pack(), connected_cell_format_payload(), generate_srv(), get_random_virtual_addr(), and var_cell_pack_header().

◆ set_uint64()

static void set_uint64 ( void *  cp,
uint64_t  v 
)
inlinestatic

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

Definition at line 96 of file bytes.h.

◆ set_uint8()

static void set_uint8 ( void *  cp,
uint8_t  v 
)
inlinestatic

Store an 8-bit value from v to cp.

◆ tor_htonl()

static uint32_t tor_htonl ( uint32_t  a)
inlinestatic

Convert a 32-bit value from host order to network order (big-endian).

Definition at line 163 of file bytes.h.

Referenced by ope_get_cipher(), tor_htonll(), and tor_ntohl().

◆ tor_htonll()

static uint64_t tor_htonll ( uint64_t  a)
inlinestatic

Return a uint64_t value from a in network byte order.
