|
* \brief Bridge PJPROJECT logging to Asterisk logging.
|
|
* \author David M. Lee, II <dlee@digium.com>
|
|
*
|
|
* PJPROJECT logging doesn't exactly match Asterisk logging, but mapping the two is
|
|
* not too bad. PJPROJECT log levels are identified by a single int. Limits are
|
|
* not specified by PJPROJECT, but their implementation used 1 through 6.
|
|
*
|
|
* The mapping is as follows:
|
|
* - 0: LOG_ERROR
|
|
* - 1: LOG_ERROR
|
|
* - 2: LOG_WARNING
|
|
* - 3 and above: equivalent to ast_debug(level, ...) for res_pjproject.so
