NSPR LOG FILE 编辑

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 NSPR_LOG_FILE is not in the environment, then log output is written to stdout or stderr, depending on the platform.  Set 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 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.
