what is PTR32 ATTRIBUTE

Hi,

I am working on 2 programs say, TKKS and TKS5. TKKS is written in assembler and uses 4 byte address while TKS5 in CPP and uses 8 byte address
I get a lot of dumps in TKS5 when input data is passed to it by TKKS.
I have been advised that TKS5 should add a couple of PTR32 definitions in its parameter list definition that it gets from TKKS.

struct Input_Parameters {
pFKSSTR FKK_Lst; //Input data passed by TKKU AND TKKS
pFKSSTR CCN_Lst; //Input data passed by TKKU AND TKKS

Can someone let me know how to add these PTR32 definitions?

So you are using a 64bit compiler for CPP and trying to interface your program with a 32bit assembly program? In order to make your pointer definitions 32bits you need to look at the stdint header file of your C++ compiler to see how it defines a 32bit int. You should see a typedef along the lines of uint32_t. If you were to declare a pointer to a 32bit integer you would use it like:

Code:

---

uint32_t* ptr32;

---

This creates a 32bit integer pointer named ptr32.

Thank you Andrew.
This has been very helpful:biggrin:

32-bit pointer is not a pointer which points to a 32-bit integer, but a pointer that occupies 4 bytes in the memory.

@Ariyana: I guess you want to share integers, not pointers...
