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