17// 3// <log/log.h> has replaced this file and all changes should go there instead.
18// C/C++ logging functions. See the logging documentation for API details. 4// This path remains strictly to include that header as there are thousands of
19// 5// references to <utils/Log.h> in the tree.
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.
