qb_log_from_external_source_va2(3)
qb_log_thread_start(3)
Start the logging pthread.
qb_log_target_user_data_get(3)
Retrieve the user data set by either qb_log_custom_open or qb_log_target_user_data_set.
qb_log_tags_stringify_fn_set(3)
Set the callback to map the 'tags' bit map to a string.
qb_log_file_reopen(3)
