  • Article

This example creates a directory for symbols and the xperf SymCache, sets the symbol path to use a local cache and the Microsoft public symbol server, traces heap allocations for notepad.exe, creates 2 summary reports, and launches the xperf viewer.

if not exist c:\TestSymbols md c:\TestSymbols
if not exist c:\TestSymCache md c:\TestSymCache
if not exist TestCullFuncs.txt echo. >TestCullFuncs.txt

set _NT_SYMBOL_PATH=srv*c:\TestSymbols*http://msdl.microsoft.com/download/symbols;
set _NT_SYMCACHE_PATH=c:\TestSymCache
