Detailed Description

Endianness conversion functions.

This set of functions converts values between the local system and a external one. It is inspired from the htonl-like functions from the standard C library.

Exemple:

  struct eth_header   *header = get_header();  // get pointer on Eth II packet header
  uint16_t            eth_id;                  // will contain the type of the packet
  eth_id = co_ntohs(header->eth_id);           // retrieve the type with correct endianness

__INLINE uint16_t co_bswap16

(

uint16_t

val16

)

Swap bytes of a 16 bits value.

The swap is done in every case. Should not be called directly.

Parameters:

[in]

val16

The 16 bit value to swap.

Returns:

The 16 bit swapped value.

__INLINE uint32_t co_bswap32

(

uint32_t

val32

Parameters:

[in]

val32

The 32 bits value to swap.

Returns:

The 32 bit swapped value.
