QuestionConversion from C to C#, Need C# Method Signature Pin

in common.c
typedef unsigned char UN_Char;
typedef enum { Valid = 0, Invalid = 1, Unknown = -999 } AppResponseCode;


Method in SomeApi.C , need to Call from C#

static AppResponseCode SomeFunction(UN_Char ** vUC1PtrPtr,size_t * vSize1Ptr, UN_Char * vUC2Ptr,size_t vSize2, FILE *  inputFile, char * vcharPtr)


I tried to add reference of provided C application DLL but Error appear
A Reference to '.....\SomeApi.DLL' could not be added. Please make sure that the file is accessible, and that it is valid assembly or COM Component


So the other option I have is to use DLLImport

[DllImport("SomeAPI.dll", CharSet = CharSet.Unicode)]
public static extern AppResponseCode SomeFunction( ????? ) ;


But I don't know what parameter types I had to pass for Return and Calling parameters to Call and obtain value from SomeFunction()

PS: Though I have source code for Complete C application but I can't re-compile it or modify it, I am only allowed to work with available Exe/DLL
