Import C-Code does't work for volatile in a typedef

Hi,

all typedefs which have a volatile are completely ignored. E.g.:

typedef volatile int vbool_t;

No generation of a Class, no error message.

Thanks for your help.

Kind regards,

Late answer, but anyway.
Does such a typedef really make sense, I thought the 'volatile' keyword should apply for particular instances of a type, not to the type itself (though the C compiler might accept such thing)?

Hi Günther,

your are right in saying that the volatile keyword makes only sense in the context of an instance. This is in fact true for all typedefs.

A good way of thinking of typedefs is to call them an Alias to have an easy to read definition of an instance / variable.

Besides, it is common practice in the realm of embedded to use such typedefs.

I sent a bug report to SPARX and two days later I got a *.xml file to fix the known problem.

Yeah I know, there are often silly things done in embedded realm if the compiler accepts it. The other way to place 'volatile' when declaring instances is still giving better readable intend IMHO.

I sent a bug report to SPARX and two days later I got a *.xml file to fix the known problem.

I guess they fixed s.th. for the C parsing process. Can you tell what kind of XML that was and if the error was also fixed in the next standard version.

Hello Günther,

1. The bug is fixed in 10 Beta 2

2. *.xml file for MDG technology folder

Code: [Select]

<MDG.Technology version="1.0">
 <Documentation id="12093714" name="Fix Issue: 12093714" version="1.0" notes="Temporary workaround for issue 12093714, where C parsing fails on volatile"/>
