[sqlite] How to code this Std_Call?

[Bart Smissaert]

Been working with this project:
https://sqliteforexcel.codeplex.com/
and further enhanced that SQLite3_StdCall.dll with more SQLite functions.
As said before I don't know C, but can work things out by looking at other
functions.
Now stuck though on a complex one, sqlite3_create_function.

In the SQLite3_StdCall project, loaded in MS Visual Studio 2013 there is a
file sqlite3.h, which has this:

int sqlite3_create_function(
  sqlite3 *db,
  const char *zFunctionName,
  int nArg,
  int eTextRep,
  void *pApp,
  void (*xFunc)(sqlite3_context*,int,sqlite3_value**),
  void (*xStep)(sqlite3_context*,int,sqlite3_value**),
  void (*xFinal)(sqlite3_context*)
);

Then there is the file SQLite3_StdCall.c, which should have something like
this:

SQLITE3_STDCALL_API int __stdcall sqlite3_create_function(
 sqlite3 *pDb,
 const char *zFunctionName,
 int nArg,
 int eTextRep,
 void *pApp,
 void(*xFunc)(sqlite3_context*, int, sqlite3_value**),
 void(*xStep)(sqlite3_context*, int, sqlite3_value**),
 void(*xFinal)(sqlite3_context*)
 )
{
 return sqlite3_create_function(
  pDb,
  zFunctionName,
  nArg,
  eTextRep,
  pApp,
  xFunc,
  xStep,
  xFinal);
}

The problem is with the last 3 void arguments. I don't know how to code
this in the return section.
I know this is off-topic, but maybe somebody can shed some light on this.
