GetArgumentDisplacement(Il2cpuMethodInfo, UInt16)

This methods gives the full displacement for an argument. Arguments are in "reverse" order: 

public static int Add(int a, int b)
In this situation, argument b is at EBP+8, argument A is at EBP+12

After the method returns, the return value is on the stack. This means, that when the return size is larger than the total argument size, we need to reserve extra stack: 

public static Int64 Convert(int value)
In this situation, argument 
value
is at EBP+12

Declaration
public static int GetArgumentDisplacement(Il2cpuMethodInfo aMethod, ushort aIndex)
Parameters
Type Name Description
Il2cpuMethodInfo aMethod
System.UInt16 aIndex
Returns
Type Description
System.Int32
