MISRA Compliance

The coreJSON library files conform to the MISRA C:2012 guidelines, with some noted exceptions. Compliance is checked with Coverity static analysis. Deviations from the MISRA standard are listed below:

Ignored by Coverity Configuration

Deviation Category Justification
Directive 4.9 Advisory Allow inclusion of function like macros.
Rule 3.1 Required Allow nested comments. C++ style // comments are used in example code within Doxygen documentation blocks.
Rule 8.13 Advisory Allow one function to have a char * argument without const qualifier.
Rule 15.4 Advisory Allow more then one break statement to terminate a loop.
Rule 19.2 Advisory Allow a union of a signed and unsigned type of identical sizes.
Rule 20.12 Required Allow use of assert(), which uses a parameter in both expanded and raw forms.

Flagged by Coverity

Deviation Category Justification
Rule 2.5 Advisory A macro is not used by the library; however, it exists to be used by an application.
Rule 8.7 Advisory API functions are not used by the library; however, they must be externally visible in order to be used by an application.

Suppressed with Coverity Comments

Deviation Category Justification
Rule 11.3 Required False positive - the rule permits type qualifiers to be added.
