示例1: write
void TLUserData::write(TLFrame& dest, size_t& wp) const
{
#if 1
// First write TP-User-Data-Length
dest.writeField(wp,mLength,8);
// Then write TP-User-Data
// This tail() works because UD is always the last field in the PDU.
BitVector ud_dest = dest.tail(wp);
mRawData.copyTo(ud_dest);
ud_dest.LSB8MSB();
#else
// Stuff we don't support...
assert(!mUDHI);
assert(mDCS==0);
unsigned numChar = strlen(mData);
dest.writeField(wp,numChar,8);
// This tail() works because UD is always the last field in the PDU.

for (unsigned i=0; i<numChar; i++) {
