<glog/logging.h>It is the core header file of Google Logging Library (glog). glog provides a powerful logging tool for C++, especially when used with other Google libraries, such as gflags.
1. Purpose
- Generation of log messages : You can easily log messages anywhere in your code.
- Log level control : For example, you can choose to log only error messages and ignore information or debug messages.
- Log destination control : By default, logs are written to a file, but you can change this to redirect them elsewhere, such as the console.
- Log cutting : Automatically cut logs based on size or time.
- Error handling : Stack traces can be automatically logged when fatal errors are encountered.
