// <log/log.h> has replaced this file and all changes should go there instead.

// C/C++ logging functions.  See the logging documentation for API details.

// This path remains strictly to include that header as there are thousands of

//

// references to <utils/Log.h> in the tree.

// 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.
