And here's some code:

var dbghelp = require('dbghelp.js');
	
var BinFile = "D:/win32k/win32kbase.sys";
var PdbFile = '';

var hProcess = null;
var pWin32kBase = null;

dbghelp.SymInitialize( hProcess , 'c:/symbols' , false );

PdbFile = dbghelp.SymGetSymbolFile( hProcess , BinFile )
    
printf('[SymGetSymbolFile]  %s \n' , PdbFile );

pWin32kBase = dbghelp.SymLoadModuleFile( hProcess , BinFile );

printf('[SymLoadModuleFile]  %s \n' , pWin32kBase );

var a = dbghelp.SymGetAddrFromName(hProcess , "gpW32FastMutex" );

printf( "gpW32FastMutex = %p \n" , a );

dbghelp.SymGetNameFromAddr(hProcess , a );

dbghelp.SymCleanup( hProcess );
