示例1: memcpy
void DS::Stream::writeSafeString(const ST::string& value, DS::StringType format)
{
if (format == e_StringUTF16) {
ST::utf16_buffer buffer = value.to_utf16();
uint16_t length = value.size() & 0x0FFF;
ST::utf16_buffer work;
char16_t* data = work.create_writable_buffer(length);
memcpy(data, buffer.data(), length * sizeof(char16_t));
for (uint16_t i=0; i<length; ++i)
data[i] = ~data[i];
write<uint16_t>(length | 0xF000);
writeBytes(data, length * sizeof(char16_t));
write<char16_t>(0);
} else {
ST::char_buffer buffer = (format == e_StringUTF8) ? value.to_utf8()
: value.to_latin_1(ST::substitute_invalid);
uint16_t length = value.size() & 0x0FFF;
ST::char_buffer work;
char* data = work.create_writable_buffer(length);
memcpy(data, buffer.data(), length * sizeof(char));
