## Detailed Description

Macros and functions for automatic endianness conversion.

## Macro Definition Documentation

#define be16_to_cpu | ( |  | x | ) | SwapEndian_16(x)

Performs a conversion between a Big Endian encoded 16-bit piece of data and the Endianness of the currently selected CPU architecture.

On big endian architectures, this macro does nothing.

Note
  This macro is designed for run-time conversion of data - for compile-time endianness conversion, use BE16_TO_CPU instead.

Parameters

  x | Data to perform the endianness conversion on.

Returns
  Endian corrected version of the input value.

Definition at line 167 of file Endianness.h.

#define BE16_TO_CPU | ( |  | x | ) | SWAPENDIAN_16(x)

Performs a conversion between a Big Endian encoded 16-bit piece of data and the Endianness of the currently selected CPU architecture.

On big endian architectures, this macro does nothing.

Note
  This macro is designed for compile-time conversion of data - for run-time endianness conversion, use be16_to_cpu instead.

Parameters

  x | Data to perform the endianness conversion on.

Returns
  Endian corrected version of the input value.
