c-log是一個穩(wěn)定，高效，多線程安全，易用，簡單的C/C++ 日志庫，在github主頁上有豐富的測試case，后續(xù)將會推遲直接輸出到scribe等集中式日志收集中間件上，幫助用戶更好的收集，分析日志

示例代碼：

log_init(LL_TRACE, "mysql", "./log/");
log_notice("%s [time:%d]", "test calling log", time(NULL));
log_debug("debug msg,only write to log when the loglevel bigger than or equal to debug [time:%d]", time(NULL));
log_warn("warnning msg will be writing to the error files [time:%d]", time(NULL));
log_error("you also can change  number of output files by rewrite the macro_define.h");
