C struct byte
WebstructName Mystruct; char *charpointer; charpointer = (char*) &Mystruct; structName *Mystruct2; Mystruct2 = (structName*) charpointer; So you just make a pointer to a char, and then you give it as value the pointer to your struct, casted to char pointer. Quite similar to the union option tbh, with both some small pros and cons.

WebStructures (also called structs) are a way to group several related variables into one place. Each variable in the structure is known as a member of the structure. Unlike an array, … WebAs you can see, there is 1 byte of unclaimed space (1 padding byte) between the boolean b and the anonymous union containing i. You could copy the whole structure to an array of bytes (memmove() or memcpy()) and then inspect the byte value that was copied, but that is barely legitimate and may not be reliable. Similarly in reverse, though the ...
WebMar 7, 2016 · This behavior is chosen so that the bytes of a packed struct correspond exactly to the layout in memory of the corresponding C struct. To handle platform-independent data formats or omit implicit pad bytes, use standard size and alignment instead of native size and alignment: see Byte Order, Size, and Alignment for details.
