minus-square@FizzyOrange@programming.devlinkfedilink2•12 days agoWhat makes you think it’s making a pointer? Nobody said anything about that.
minus-square@zygo_histo_morpheus@programming.devlinkfedilink2•12 days agoOh my bad I don’t know where I got that from lol
minus-square@FizzyOrange@programming.devlinkfedilink3•12 days agoNw. You’re also wrong about endianness. This function would be written exactly the same irrespective of endianness: uint32_t u16_high_low_to_u32(uint16_t high, uint16_t low) { return (high << 16) | low; } That is endian agnostic.
