EC2 掛載 S3 空間作為備份磁區

須安裝 s3fs


s3fs -o use_cache=/media/xxxx/tmp_cache backup /mnt/s3-backup

C++ boolean to string

備份用

libjingle on android  印 Log

inline const char * const BooleanToString(bool b)

{

  return b ? "true" : "false";

} 

 __android_log_print(ANDROID_LOG_ERROR, "Tag: ", "Text: %s", BooleanToString(a));
