## Detailed Description

Provides a variable length argument message logging abstraction.

This class is very flexible since it allows formatted error messages to be printed in a thread-safe manner to various locations, such as stdout, stderr, cerr, a distributed logger, etc. The current message is also kept in a thread-specific storage location (threads spawned using ACE_Thread_Manager automatically get an ACE_Log_Msg object that inherits the spawning thread's settings), which can be used to communicate errors between framework methods and callers. A message is logged by the log() method, only if the message priority is currently enabled. Moreover, only the current log message is stored here -- it will be overwritten by the subsequent call to log().

The ACE_Log_Msg class uses two priority masks to control its logging behavior. The `priority_mask_` object attribute is thread- specific and specifies the priority levels logged by the thread. The `process_priority_mask_` class attribute is not thread-specific and specifies the priority levels that will be logged by all threads in the process. By default, all levels are disabled for `priority_mask_` and all levels are enabled for `process_priority_mask_` (i.e. the process-wide mask controls the settings, and each instance can expand on it if desired). Both priority masks can be modified using the priority_mask() method of this class.
