do you have other calls like that? error could be caused before of that point (does crash occour if that method is not called?)
would you mind trying stdcall instead of cdecl?

TareOP•5/31/24, 8:55 AM

no dice with stdcall

TareOP•5/31/24, 8:55 AM

same error at the same place

deprecatio•5/31/24, 10:11 AM

ok then so does just calling NativeNewContext cause a crash? because if it is then since it's so short it could be worth looking at disassembly

D

deprecatio•5/31/24, 10:14 AM

ALSO i would like to point out that the import

[DllImport(Dlls.AeroxWidgetsNative, EntryPoint = "msdfRenderContext",CallingConvention = CallingConvention.Cdecl)]
private static extern IntPtr NativeNewContext();

[DllImport(Dlls.AeroxWidgetsNative, EntryPoint = "msdfRenderContext",CallingConvention = CallingConvention.Cdecl)]
private static extern IntPtr NativeNewContext();

[DllImport(Dlls.AeroxWidgetsNative, EntryPoint = "msdfRenderContext",CallingConvention = CallingConvention.Cdecl)]
private static extern IntPtr NativeNewContext();

[DllImport(Dlls.AeroxWidgetsNative, EntryPoint = "msdfRenderContext",CallingConvention = CallingConvention.Cdecl)]
private static extern IntPtr NativeNewContext();

is pointing to

msdfRenderContext

msdfRenderContext

msdfRenderContext

msdfRenderContext and not

msdfNewContext

msdfNewContext

msdfNewContext

msdfNewContext
