NSPR_LOG_FILE ============= This environment variable specifies the file to which log messages are directed. Syntax ------ :: filespec *filespec* is a filename. The exact syntax is platform specific. Description ----------- Use this environment variable to specify a log file other than the default. If :ref:`NSPR_LOG_FILE` is not in the environment, then log output is written to ``stdout`` or ``stderr``, depending on the platform. Set :ref:`NSPR_LOG_FILE` to the name of the log file you want to use. NSPR logging, when enabled, writes to the file named in this environment variable. For MS Windows systems, you can set :ref:`NSPR_LOG_FILE` to the special (case-sensitive) value ``WinDebug``. This value causes logging output to be written using the Windows function ``OutputDebugString()``, which writes to the debugger window.
