## Member Function Documentation

## ◆ GetAddressOfArg()

virtual void * asIScriptGeneric::GetAddressOfArg | ( | asUINT | arg | ) |
| pure virtual

Parameters

  [in] | arg | The argument index.

Returns
  A pointer to the argument value.

## ◆ GetAddressOfReturnLocation()

virtual void * asIScriptGeneric::GetAddressOfReturnLocation | ( |  | ) |
| pure virtual

Returns
  A pointer to the memory where the return values is to be placed.

The memory is not initialized, so if you're going to return a complex type by value you shouldn't use the assignment operator to initialize it. Instead use the placement new operator to call the type's copy constructor to perform the initialization.

new(gen->GetAddressOfReturnLocation()) std::string(myRetValue);

The placement new operator works for primitive types too, so this method is ideal for writing automatically generated functions that works the same way for all types.

## ◆ GetArgAddress()

| pure virtual

Parameters

  [in] | arg | The argument index.

Returns
  The address argument value, which can be a reference or and object handle.

Don't release the pointer if this is an object or object handle, the asIScriptGeneric object will do that for you.

Returns
  A pointer to the object argument, which can be an object value or object handle.

Don't release the pointer if this is an object handle, the asIScriptGeneric object will do that for you.

Returns
  A negative value on error.

Return values

  asINVALID_TYPE | The return type is not a reference or handle.

Sets the address return value. If an object handle the application must first increment the reference counter, unless it won't keep a reference itself.

## ◆ SetReturnByte()

| pure virtual

Parameters

  [in] | val | The return value.

## ◆ SetReturnDouble()

virtual int asIScriptGeneric::SetReturnDouble | ( | double | val | ) |
| pure virtual

Parameters

  [in] | val | The return value.

Returns
  A negative value on error.

Return values

  asINVALID_TYPE | The return type is not a 64-bit value. Sets the double return value.

## ◆ SetReturnDWord()

virtual int asIScriptGeneric::SetReturnDWord | ( | asDWORD | val | ) |
| pure virtual

Parameters

  [in] | val | The return value.

Returns
  A negative value on error.

Return values

  asINVALID_TYPE | The return type is not a 32-bit value. Sets the 4 byte return value.

## ◆ SetReturnFloat()

virtual int asIScriptGeneric::SetReturnFloat | ( | float | val | ) |
| pure virtual

Parameters

  [in] | val | The return value.

Returns
  A negative value on error.

Return values

  asINVALID_TYPE | The return type is not a 32-bit value. Sets the float return value.

## ◆ SetReturnObject()

virtual int asIScriptGeneric::SetReturnObject | ( | void * | obj | ) |
| pure virtual

Parameters

  [in] | obj | A pointer to the object return value.

Returns
  A negative value on error.

Return values

  asINVALID_TYPE | The return type is not an object value or handle.

If the function returns an object, the library will automatically do what is necessary based on how the object was declared, i.e. if the function was registered to return a handle then the library will call the addref behaviour. If it was registered to return an object by value, then the library will make a copy of the object.

| pure virtual

Parameters

  [in] | val | The return value.

Returns
  A negative value on error.

Return values

  asINVALID_TYPE | The return type is not a 64-bit value. Sets the 8 byte return value.

## ◆ SetReturnWord()

virtual int asIScriptGeneric::SetReturnWord | ( | asWORD | val | ) |
| pure virtual

Parameters

  [in] | val | The return value.

Returns
  A negative value on error.
