If you have array defined like
dword someArray[100];

someArray contains the pointer to the first member of array.

for function pointers go to:
www.function-pointer.org

typedef int (*FuncType)( long param1, long param2 );
#define FUNCBUILDER( X ) int X ( long param1, long param2 )

FuncType FunctionArray[256];

// I use the macro FUNCBUILDER for this, especially for

//   script-accessible function writing.

FUNCBUILDER( MyFunction );

FUNCBUILDER( MyFunction ) {
  return (param1 + param2) * 2;
}

// The above macros expand to this code exactly.

int MyFunction( long param1, long param2 );

int MyFunction( long param1, long param2 ) {
  return (param1 + param2) * 2;
}


void main( void ) {
  int myReturn;

  // This syntax works... I've tried it with Borland's 32-bit 

  //   C++ Builder version 5.5, and with MSVC++ 6.0.

  FunctionArray[0] = MyFunction;

  // Henceforth, these are identical calls.

  myReturn = (FunctionArray[0])( (long)23, (long)100 );
  myReturn = MyFunction( (long)23, (long)100 );
}

Also, follow the link Kosmo gave; I've been there. It helps.
