示例1: xmlExportContent
void FlatMessageIO::xmlExportContent(
ExportContext& context) const {
context.beginContent();
// convert message to base64
ASSERT(m_message);
ssize_t flatSize = m_message->FlattenedSize();
ASSERT(flatSize);
char* flatData = new char[flatSize];
status_t err = m_message->Flatten(flatData, flatSize);
ASSERT(err == B_OK);
// make plenty of room for encoded content (encode_base64 adds newlines)
ssize_t base64Size = ((flatSize * 3) / 2);
char* base64Data = new char[base64Size];
ssize_t base64Used = encode_base64(base64Data, flatData, flatSize);
base64Data[base64Used] = '\0';
// write the data
const char* pos = base64Data;
