Summary
ByVal is a VB keyword that specifies a variable to be passed as a parameter BY VALUE. In other words, if the function or sub changes the value of the internal variable, it does not change the value of the external variable that was passed to it.

C# Signature:

[DllImport("coredll.dll", SetLastError=true)]
static extern TODO ByVal(TODO);

VB Signature:

Declare Function ByVal Lib "coredll.dll" (TODO) As TODO

User-Defined Types:

None.

Notes:

To pass a variable by reference (i.e. change the external variable to whatever value is set inside the function/sub) use ByRef before the parameter name.
