Use StreamString?:
```
#include "lldb/Utility/StreamString.h"
void PrintfTruncated(int right_pad, const char *format, ...)
__attribute__((format(printf, 3, 4))) {
va_list args;
va_start(args, format);
StreamString strm;
strm.PrintfVarArg(format, args);
va_end(args);
PutCStringTruncated(right_pad, strm.GetData());
}
```
