Is there a way to enforce specific endianness for a C or C++ struct?

Question

I\'ve seen a few questions and answers regarding to the endianness of structs, but they were about detecting the endianness of a system, or converting data between the two d

Answer 1

Boost provides endian buffers for this.

For example:

#include 
#include 

using namespace boost::endian;

struct header {
    big_int32_buf_t     file_code;
    big_int32_buf_t     file_length;
    little_int32_buf_t  version;
    little_int32_buf_t  shape_type;
};
BOOST_STATIC_ASSERT(sizeof(h) == 16U);
