AUTOSAR C++14 Rule M0-1-10

Every defined function should be called at least once

expand all in page

Description

Rule Definition

Every defined function should be called at least once.

Rationale

If a function with a definition is not called, it might indicate a serious coding error. For instance, the function call is unreachable or a different function is called unintentionally.

Polyspace Implementation

The checker detects situations where a static function is defined but not called at all in its translation unit.

Troubleshooting

If you expect a rule violation but Polyspace® does not report it, see Diagnose Why Coding Standard Violations Do Not Appear as Expected.

Examples

expand all

static void func1() {
}

static void func2() { //Noncompliant
}

void func3();

int main() {
    func1();
    return 0;
}

The static function func2 is defined but not called.

The function func3 is not called either, however, it is only declared and not defined. The absence of a call to func3 does not violate the rule.
