Re: Prototype for QSYRTVAI

Thanks for the explanation. I also missed that the parameter in question was an output parameter which explains why its prototype was different.

    Both "int" and "int *" behave the same for a linkage(OS) call.

    It says that all arguments except pointers and aggregates are copied to 
    a temporary and the address of the temporary is passed.
    
    So if the prototype has just "int", it will pass a pointer to the 
    integer parameter. If the parameter is "int *", it's already a pointer, 
    so it will just pass the parameter directly.
