Macro Definition Documentation

◆ SPA_LOG_IMPL_DEFINE

#define SPA_LOG_IMPL_DEFINE (   name)

◆ SPA_LOG_IMPL_INIT

◆ SPA_LOG_IMPL

◆ SPA_LOG_TOPIC_DEFAULT

#define SPA_LOG_TOPIC_DEFAULT   NULL

The default log topic.

Redefine this in your code to allow for the spa_log_* macros to work correctly, e.g:

struct spa_log_topic *mylogger;
#undef SPA_LOG_TOPIC_DEFAULT
#define SPA_LOG_TOPIC_DEFAULT mylogger
