1# async_safe logging 2 3This library provides an async_safe implementation for formatting and writing log messages to logd. 4 5Note that the liblog implementation connects a single socket to logd and uses a RWLock to manage 6it among threads, whereas these functions connect to liblog for each log message. While it's 7beneficial to have this lock-free and therefore async_safe mechanism to write to logd, connecting 8a socket for each message does not scale well under load. It was also determined to be too 9costly to connect a socket for each thread as some processes, such as system_server, have over 100 10threads. Therefore, we maintain these two separate mechanisms. 11
