20 // We'd like these to be available from C code (in case we import some from
21 // somewhere), so this has a C interface.
22 //
23 // The output will be correct when the log file is shared between multiple
24 // threads and/or multiple processes so long as the operating system
25 // supports O_APPEND. These calls have mutex-protected data structures
26 // and so are NOT reentrant. Do not use LOG in a signal handler.
