The information in this article applies to:
  • Microsoft Windows Software Development Kit (SDK) for Windows version 3.1

SUMMARY

In Windows version 3.1, a Windows-based application can obtain the amount of free system resources in two ways:

  1. By calling the GetFreeSystemResources() function, which is exported by USER.EXE

  2. By calling the SystemHeapInfo() function, which is exported by the TOOLHELP.DLL dynamic-link library

Under Windows 3.0, the GetFreeSystemResources() function is not available. If TOOLHELP.DLL is present, a Windows 3.0 application can use SystemHeapInfo(). If TOOLHELP.DLL is not present, there is no supported method for a Windows 3.0 application to obtain the amount of free system resources. Keywords : kb16bitonly TlsHlp
