- Type: System.IntPtr
A pointer to the method to marshal.
- Type: System.IntPtr
A pointer to the method signature.
- Type: System.Int32
The number of bytes in pbSignature.
Return ValueType: System.IntPtr
A pointer to the thunk that will marshal a call from pfnMethodToWrap.

This method uses SecurityAction.LinkDemand to prevent it from being called from untrusted code; only the immediate caller is required to have SecurityPermissionAttribute.UnmanagedCode permission. If your code can be called from partially trusted code, do not pass user input to Marshal class methods without validation. For important limitations on using the LinkDemand member, see Demand vs. LinkDemand.
