|
* @brief This log system supports wrapping multiple outputs into one
|
||
|
|
* log message. This is useful for outputting variable-length logs
|
||
|
|
* without additional memory overhead (the buffer for concatenating
|
||
|
|
* the message), e.g. exception stack trace, which cannot be printed
|
||
|
|
* by a single log calling without the help of an additional buffer.
|
||
|
|
* Avoiding additional memory buffer is useful for resource-constraint
|
||
|
|
* systems. It can minimize the impact of log system on applications
|
||
|
|
* and logs can be printed even when no enough memory is available.
|
||
|
|
* Functions with prefix "_" are private functions. Only macros that
|
||
|
|
* are not start with "_" are exposed and can be used.
