Logging functions of PipeWire.
Logging is performed to stdout and stderr. Trace logging is performed in a lockfree ringbuffer and written out from the main thread as to not block the realtime threads.
◆ PW_LOG_TOPIC_STATIC
#define PW_LOG_TOPIC_STATIC |
( |
|
var, |
|
|
|
topic |
|
) |
| |
Declare a static log topic named var.
The usual usage is:
#define PW_LOG_TOPIC_DEFAULT my_topic
void foo() {
}
#define PW_LOG_TOPIC_STATIC(var, topic)
Declare a static log topic named var.

- Returns
- the global log
◆ pw_log_set_level()
Configure the logging level.
Configure the logging level.
- Parameters
