Macros and functions for forced byte reordering.
#define SWAPENDIAN_16 | ( | x | ) | (uint16_t)((((x) & 0xFF00) >> 8) | (((x) & 0x00FF) << 8)) |
Swaps the byte ordering of a 16-bit value at compile-time. Do not use this macro for swapping byte orderings of dynamic values computed at runtime, use SwapEndian_16() instead. The result of this macro can be used inside struct or other variable initializers outside of a function, something that is not possible with the inline function variant.
x | 16-bit value whose byte ordering is to be swapped. |

#define SWAPENDIAN_32 | ( | x | ) |
Swaps the byte ordering of a 32-bit value at compile-time. Do not use this macro for swapping byte orderings of dynamic values computed at runtime- use SwapEndian_32() instead. The result of this macro can be used inside struct or other variable initializers outside of a function, something that is not possible with the inline function variant.
x | 32-bit value whose byte ordering is to be swapped. |

inlinestatic |
Function to reverse the byte ordering of the individual bytes in a 16 bit value.
Word | Word of data whose bytes are to be swapped. |
Definition at line 393 of file Endianness.h.
Function to reverse the byte ordering of the individual bytes in a 32 bit value.
DWord | Double word of data whose bytes are to be swapped. |
Definition at line 422 of file Endianness.h.
|
inlinestatic |
Function to reverse the byte ordering of the individual bytes in a n byte value.
[in,out] | Data | Pointer to a number containing an even number of bytes to be reversed. |
Length | Length of the data in bytes. |
