V3550. AUTOSAR. The identifier 'main' should not be used for a function other than the global function 'main'.

Mar 11 2021

This diagnostic rule is based on the software development guidelines developed by AUTOSAR (AUTomotive Open System ARchitecture) .

The 'main' function should only be present in the global namespace. This way a developer will be sure - if the 'main' function appears, it is always the entry point to the program.

The analyzer issues a warning for the following code example:

namespace N1
{
  int main();
}

Another code example that triggers the analyzer:

namespace
{
  int main();
}

If we rewrite the code by the rule, we will get the following:

namespace N1
{
  int start();
}

This diagnostic is classified as:

  • AUTOSAR-M7.3.2
