convert big endian to little endian in C [without

Question

I need to write a function to convert big endian to little endian in C. I can not use any library function.

Answer 1

Will this work / be faster?

 uint32_t swapped, result;

((byte*)&swapped)[0] = ((byte*)&result)[3];
((byte*)&swapped)[1] = ((byte*)&result)[2];
((byte*)&swapped)[2] = ((byte*)&result)[1];
((byte*)&swapped)[3] = ((byte*)&result)[0];
