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