Help¶

If queue with pending log messages is full, oldest log message is dropped if queue is still full after requested time (-1 is forever). Logger thread is blocked for that period, thus long timeout impacts other logger backends and must be used with care.

Direct dependencies¶

SHELL_BACKEND_RTT && SHELL_BACKENDS && SHELL

(Includes any dependencies from ifs and menus.)
