Welcome to the MISRA discussion forum

For Dir 4.8 the document is not clear about whether the following case should be considered as non-compliant.

/* def.h */
struct SomeType
{
/* Object implementation */
}

/* no-use.c */
#include def.h
/* Do something. But no use of SomeType at all. */

The example doesn't involve any pointer but indeed goes against the rationale since the implementation details of SomeType is not needed in no-use.c and it should at least be opaque. Also, logically, "no pointer" implies "a pointer is never dereferenced", since there is no such pointer to begin with.

Please kindly help to advise. Thanks!

Does the following expression comply with Rule 13.2?

(x = a) && (x = b)

What if it is preceded by the following declaration?

int a = 0;

Thanks,

Hi,
will MISRA AC SLSF guideline be updated?
If yes, is there a planned release date?

Thank you in advance,

Why is
#include "c:\headers\measurement_regs.h "
non compliant to rule 20.2 due to \ in the path?

MISRA AC SLSF 022 states that a model information block is required for every subsystem. Does application of this rule include virtual subsystems, or only "true" (i.e., atomic or nonvirtual) subsystems?
Stated differently: Virtual subsystems should share the identity and origin of the parent model, atomic subsystem, or library to which they belong (the rationale for rule 022), so do they need that information reiterated in their own model information block?
I would appreciate knowing what the community consensus is on this topic.

Hello,

I have one question regarding the copyright of the Exemplar Suite. I want to share this with my colleagues in my company, so am i allowed to do that?

We have an internal tool for sharing , can i upload these examples there?

It will be accessed in my company only.

Thank you.

Hello,

I am getting MISRA 5.2 rule violation in my project. The code for which i am getting violation is a structure that is declared as extern in one header file. The code example is as under

1.h

I want to just clarify that following is a MISRA violation before using it in my code. I am calling one function from a file as under:

Hello,

I have an issue with MISRA 9.1 rule. In my code i have a "if" loop and inside that a variable is initialized and then is read after that. But when i do static analysis using pclint then i have a warning for 9.1 rule. Below is my code :

struct mgm2_info_return msg_ascu_info;

Hello,

I am facing an issue relating to rule 8.3. I am fixing MISRA violations in the project. The following code line is where i have issue:

in one of the files in the project i have the following code line:

dies->DrvPosn_D_SvRc_Rq = get_DrvPosn_D_SvRc_Rq();

get_DrvPosn_D_SvRc_Rq() is defined in other file as below:

tm_uint8 get_DrvPosn_D_SvRc_Rq(void)
{
return cio_DrvPosn_D_SvRc_Rq;
}

When i am performing the MISRA check , i get a error at 'dies->DrvPosn_D_SvRc_Rq = get_DrvPosn_D_SvRc_Rq();' line saying that Symbol 'get_DrvPosn_D_SvRc_Rq(void)' redeclared .

All the variables have same datatype tm_uint8;

Can you point out where the issue lies?

Thank you!
