示例1: IsValidAddress
// -----------------------------------------------------------------------------
// CSdpConnectionField::IsValidAddress
// Checks if the given address is valid

//
TInt CSdpConnectionField::IsValidAddress(
const TInetAddr& aAddress,
TInt aTTL,
TUint aNumOfAddress ) const
{
TInt err( KErrSdpCodecConnectionField );

// Address has to be either of type IP4 or IP6
// If IP4 and multicast then it must contain TTL attribute
// If IP4 and unicast then it must NOT contain TTL and must have 1 address
