std::span::size_bytes(3) C++ Standard Libary std::span::size_bytes(3) NAME std::span::size_bytes - std::span::size_bytes Synopsis constexpr size_type size_bytes() const noexcept; (since C++20) Returns the size of the sequence in bytes. Parameters (none) Return value The size of the sequence in bytes, i.e., size() * sizeof(element_type). Example // Run this code #include <cstdint> #include <span> int main() { constexpr static std::int32_t a[]{1, 2, 3, 4, 5}; constexpr static std::span s{a}; static_assert ( sizeof(int32_t) == 4 && std::size(a) == 5 && sizeof a == 20 && s.size() == 5 && s.size_bytes() == 20 ); } See also size returns the number of elements in the sequence (C++20) (public member function) http://cppreference.com 2024.06.10 std::span::size_bytes(3)
