[IL2CPP] Plugin function returning incorrect unhdefined bool

IL2CPP

-

Steps to reproduce:
1. Download the attached project and open "SampleScene" scene
2. Enter play mode
3. Notice that returned undefined bool is false
4. Build project with IL2CPP backend
5. Notice that returned undefined bool is true

Expected results: Player build with IL2CPP should return false bool
Actual results: Player build with IL2CPP returns true bool

Reproduced with: 2019.2.0a1, 2019.1.0a14, 2018.3.3f1, 2017.4.18f1
Tested on UWP and Standalone (Windows 10) platforms

  1. Resolution Note:

    By default, p/invoke methods that return a C++ bool marshal that a four-byte value. In order to return it as a one-byte value, add the following attribute to the extern method in C#:

    [return : MarshalAs(UnmanagedType.U1)]

    This will cause IL2CPP to treat the return value as a C++ bool.
