73 * Like bt_lib_log(), but also appends a cause to the current thread's
76 * Note that, unlike bt_lib_log(), this function does check that logging
77 * is enabled for level `lvl` before logging. This is to ensure that,
78 * even though logging is disabled, the function still appends an error
79 * cause, as the error reporting system does not rely on logging.
81 * Use one of the BT_LIB_LOG*_APPEND_CAUSE() macros above instead of
82 * calling this function directly.
