is File Include Guard applicable/reviewed with Rule 19.4 ? - edgartorres0523 - 18-07-2014
Hi team,
First of all, I want to thank you for supporting people with this amazing forum that is very useful , "Thumbs up".
I have the following File Include Guard:
#ifndef _MYHEADER_H_ // beginning
#define _MYHEADER_H_
...
#endif // end
My question is if File Include Guards have to be applicable/reviewed with the MISRA-C:2004 Rule 19.4 ?
Thanks and Best Regards.

We agree that it is unclear whether the following line violates rule 19.4.
Quote:#define _MYHEADER_H_
The intention was that C macros with empty replacement lists should be permitted, as is shown in the example for rule 19.15
