// MinidumpFileWriter writer;

// TypedMDRVA<MDRawHeader> header(&writer_);
// header.Allocate();
// header->get()->signature = MD_HEADER_SIGNATURE;

// An alternative is to use SetFile and provide a file descriptor:
// MinidumpFileWriter writer;
// writer.SetFile(minidump_fd);
// TypedMDRVA<MDRawHeader> header(&writer_);
// header.Allocate();
// header->get()->signature = MD_HEADER_SIGNATURE;
//  :
