目前EasyLogger的功能并不支持多进程安全,所以如果单纯的写到文件,会有覆盖现象。
当然EasyLogger的架构就是为了方便扩展,达到个人使用的任意要求。如果是linux系统,可以使用system v或者posix的信号量来做到多进程安全。
具体的说,使用信号量在elog_port_init,elog_port_output_lock,pthread_mutex_unlock中替换掉pthread_mutex操作即可。

非常抱歉,pthread_mutex_unlock粘错了,应该是elog_port_output_unlock。

好的,非常谢谢!如果是写到控制台,目前就可以了吗?你们官方会添加这个需求吗?
from easylogger.
如果写到控制台就没有多进程的概念了,EasyLogger本身是支持线程安全的。重要查看各平台的elog_port_output函数的定义。
关于写文件的需求,我近期抽时间添加下,到时候推送给作者,如果没问题,应该可以合并到主线上。敬请期待!
