/DELAY
(Delay load import settings)
Linker options to control delayed loading of DLLs at runtime.
/DELAY:UNLOAD
/DELAY:NOBIND
The /DELAY
option controls delayed loading of DLLs:
The
/DELAY:UNLOAD
qualifier tells the delay-load helper function to support explicit unloading of the DLL. The Import Address Table (IAT) is reset to its original form, invalidating IAT pointers and causing them to be overwritten.If you don't select
/DELAY:UNLOAD
, any call to__FUnloadDelayLoadedDLL
will fail.The
/DELAY:NOBIND
qualifier tells the linker not to include a bindable IAT in the final image. The default is to create the bindable IAT for delay-loaded DLLs. The resulting image can't be statically bound. (Images with bindable IATs may be statically bound before execution.) For more information, see/BIND
.If the DLL is bound, the helper function attempts to use the bound information instead of calling
GetProcAddress
on each of the referenced imports. If either the timestamp or the preferred address doesn't match the ones in the loaded DLL, the helper function assumes the bound IAT is out of date. It continues as if the bound IAT doesn't exist./DELAY:NOBIND
causes your program image to be larger, but can speed load time of the DLL. If you never intend to bind the DLL,/DELAY:NOBIND
prevents the bound IAT from being generated.
To specify DLLs to delay load, use the /DELAYLOAD
option.
Open the Property Pages dialog box for the project. For more information, see Set compiler and build properties.
Select the Configuration Properties > Linker > Advanced property page.
Modify the Unload delay loaded DLL property or the Unbind delay loaded DLL property. Choose OK or Apply to save your changes.
