paged memory with far and rptr

philipp_k — Thu, 02 Dec 2010 18:09:02 GMT

Hello guys,

I am using a variable mapped to banked RAM: char MyArray[5]

Now I am trying to create a pointer to this variable: char * __rptr localArrPtr = MyArray

Is this the right way ?

What is the difference between a __far pointer and a __rptr pointer ?

How do I call a function with that pointer ?

void editArray ( char index, char * __rptr ArrPtr)

Thanks for your help

Philipp

Hello

Attached application note from the {Install}\Help\PDF directory provides more details for the various type of pointers.

Basically rptr pointer are accessed using RPAGE register, whereas far pointer are accessed using GPAGE register.
