Rule M16.10

[dg1980]

From ISO C standard:

The strncpy function returns the value of s1.

So, no error information to test and hence no violation of 16.10.

If you upgrade to MISRA C 2012 you can use this explicit exception for function return values:

Code:

(void)strncpy(MyStr1,MyConstStr, sizeof(MyConstStr);

I did not find a corresponding entry in the obsolete 2004 standard.
