On some work we are doing we don't want to have to link IGGCSI00 (Catalog
Services Interface) into our C program. We have an assembler routine that will
load the routine and pass back the address to the caller and I have verified
that the function pointer now points to the requested module. But when I call
it, I get a S0c4 which I'm pretty sure because the parameter list is not in OS
format, its C based.
Now my dilemma is to specify that the calling convention for this function
pointer is OS and not C.
I can not figure out how to code the #pragma linkage(?????, OS).
This is the definition for the function pointer.
int (*pIggCsi00)(PARM1, PARM2, PARM3);
Here is the call to do the load.
int fnLoadModule("IGGCSI00", (void(**)()) &pIggCsi00));
On return from the load routine pIggCsi00 definitely points to IGGCSI00.
The call to the function is:
iReturnCode = pIggCsi00(PARM1, PARM2, PARM3);
I'm stumped.
