WebAug 24, 2024 · Also, read() does not read a value of some specified type from a pointer to bytes; it reads exactly one value of the type behind the pointer (e.g. if it is *const u8 then read() will read one byte) and returns it. If you only want to write byte contents of a structure into a vector, you can obtain a slice from the raw pointer: Webuint8_t is Standard C and represents an unsigned 8-bit integral type.
