MISRA C:1998 Rule 113
#1
Hello All.

I am running the comercial RTOS Salvo through the MISRA checker as implemented in IAR's EWARM v4.20A tool suite.

I have a struct called ecb which in turn contains a field called tcbP. ecbP is a pointer to the struct ecb. OSeligQP is a pointer to a struct tcb.

The IAR MISRA checker complains about a call to a function

Code:
OSInsPrioQ(OScTcbP, &(ecbP->tcbP));

whereas it's fine with

Code:
OSInsPrioQ(OScTcbP, &OSeligQP);

Now, I admit that I do not know MISRA views passing a parameter by reference, but it certainly doesn't disallow it. In my example, a member of a struct is being passed by reference (not by value), and is being accessed by name, as per MISRA.

So, is this legal in MISRA-C?

Thanks for any and all input.

It is not entirely apparent from your question what the tool is complaining about.

Rule 113 was not intended to preclude the use of the address of a structure member.

The intent of Rule 113 was to prevent the addressing of unnamed members of a structure.

Rule 113 is rescinded in MISRA-C:2004.

Thanks -- obviously there are tool issues to contend with as well as simply understanding the intent of the rules themselves.
