In Vector CANoe, is it possible to define a function that takes a system variable argument like the system function TestWaitForSignalMatch()?
For my use case it is not sufficient to supply the current value of the system variable because I want to pass the system variable to TestWaitForSignalMatch() or similar system functions.
The CANoe help seems to show examples:
long TestWaitForSignalMatch (Signal aSignal, float aCompareValue, dword aTimeout); // form 1
long TestWaitForSignalMatch (sysvar aSysVar, float aCompareValue, dword aTimeout); // form 3
I tried like this
void foo(sysvar aSysvar) {}
^
or this
void foo(sysvar *aSysvar) {}
^
but I get a parse error at the marked position of the sysvar keyword in both cases.
I successfully created functions that take a signal argument, but unlike the syntax in the CANoe help I have to use a pointer. This works:
void foo(signal *aSignal) {}
Obviously the documentation in the help is not correct in this point. It results in a parse error after the signal keyword when I omit the * as shown in the help:
void bar(signal aSignal) {}
^
So what's the correct syntax for defining a function that takes a sysvar argument? (if possible)
In case the version matters, I'm currently testing with CANoe 9.0.53(SP1), 9.0.135(SP7) or 10.0.125(SP6).
Yes, you can. Just define a bit further your sysvar type, not just sysvar.
System variables, with indication of type and *. Possible types: Data, Int, Float, String, IntArray, and FloatArray. Example declaration: sysvarFloat * sv
You didn't specify the CANoe SP version, so it may not be supported in older versions, but to make sure of this, search for Function parameter in Help/Index, then you should get the full list of possible function parameters you can use in your current CANoe setup. Should start like this:
