(Keeping your parentheses as is):

1. take address of image->clientData[0]:
 
&(image)->clientData[0]) 

2. cast that address to pointer to pointer to imageType: 

(imageType**)&(image)->clientData[0] 

3. dereference the pointer to pointer to imageType, yielding a pointer to
imageType:

*(imageType**)&(image)->clientData[0] 

4. assign src (a pointer to imageType) to that pointer to imageType:

(*(imageType**)&(image)->clientData[0])=(src); 

The problem here, DUMBASS, is that you never typedef'ed imageType, so
the whole thing is a FAIL.

The other question is, if you don't know what kind of data is going
to be needed, why are you using 

   int64_t clientData[CLIENT_SIZE];

instead of

   void *clientData[CLIENT_SIZE];

?
