# Interlocked64
## **NEW**: Interlocked64 for Static Linking
Intelocked64.c can be compiled into Interlocked64.obj for use with twinBASIC's new static linking feature. This enables the use of it in kernel mode, where you can't load regular DLLs. These functions are especially important there.
From an x64 developer tools prompt, or from a regular one after running vcvars64.bat, compile with: `cl.exe /c /Gw /Gy /GS- Interlocked64.c /Fo"Interlocked64.obj"`
Then import into the Miscellaneous folder of your project. After that, it's used like this:
```vba
#If Win64 Then
Import Library "/StaticLibraries/Interlocked64.obj" As Interlocked
#End If
Module MyModule
Private DeclareWide PtrSafe Function InterlockedIncrement CDecl Lib Interlocked Alias "x64InterlockedIncrement" (Addend As Long) As Long
...
```
(The CDecl is ignored on x64, but it's good practice to leave it there, in case you ever make a 32bit version, or just to remind you)
See below for the rest of the definitions in this format (it's just replacing "Interlocked64.dll" with Interlocked.
## Interlocked64.dll v1.0.1
x64 Interlocked* compiler instrinsics exported by standard DLL
The Interlocked functions are very useful for multithreading, but are not exported under x64. I suspect a toolchain lockin strategy. As these functions are not trivially recreated using higher level code than assembly (when you run down those functions, they hit intrlock.asm), I've created a simple C++ DLL to turn them back into exported functions. This is primarily intended for use in twinBASIC, but if anyone did come up with a use for it in VBA7 64bit, it would work there too-- it's just a standard DLL.
The demo application includes all of the declares, and a very simple example of using a couple.
**NOTE:** The Demo, as configured, only works when compiled:
VBx and tB don't search the app path for DLLs by default.
The typical workaround is to hard code the path, but who knows where you'll put this? An alternative is provided here **BUT IT ONLY WORKS FOR COMPILED EXES**.
To use these functions from the IDE, or without the Set dir call, you can either hard code the path or place the DLL in System32.
Update: It turns out tB has a built-in equivalent of that method that will also work under the IDE; you can use the attribute `[ SetDllDirectory (True) ]` for either individual declares, or at the module level (placing it before `Module foo` or `Clqss foo`) to apply to all API declares in that module.
