QA C Help - Rule-5.9

		MISRA C:2012 Rule-5.9: (Advisory)			Identifiers that define objects or functions with internal linkage should be unique

Amplification:

The identifier name should be unique across all name spaces and translation units. Any identifier used in this way should not have the same name as any other identifier, even if that other identifier denotes an object with no linkage.

Exception:

An inline function with internal linkage may be defined in more than one translation unit provided that all such definitions are made in the same header file that is included in each translation unit.

QAC messages that encompass this guideline:

1525 Object/function with external linkage has same identifier as another object/function with internal linkage.

1527 Object/function with internal linkage has same identifier as another object/function with internal linkage.

1528 Object with no linkage has same identifier as another object/function with internal linkage.
