Summary: The issue is on ARM builds for Windows UWP. For the C# P/Invoke API wrapper, any native method that returns the YogaValue struct throws the AccessViolationException. The issue is not with structs in general, as returning the YogaSize / YGSize struct works fine. The issue seems to be limited to structs that have an enum member. I tried a number of things to resolve the issue without changing the underlying native API for Windows. I read the ARM documentation and saw reference to variable enum sizes based on the number of enum members, so I tried to use a number of different UnmanagedType values in a [MarsalAs()] attribute on the enum member of the C# struct declaration. What ultimately worked was to return a pointer to the location of the struct, and use the System.Runtime.InteropServices.PtrToStructure API to read the struct data from that pointer. I added a few new macros that will return the struct address on Windows only, other builds are not affected. Note, I have not tested the impact of this ch Closes https://github.com/facebook/yoga/pull/459 Reviewed By: emilsjolander Differential Revision: D4652278 Pulled By: splhack fbshipit-source-id: bf7ada4da1781e3f813b3ba331974b7bded476d9 |
