$Super$$main()

Just see a function in xxx.c file as:

Code:

---

void $Sub$$main(void)
{
  // blahblah..  // does some extra setup work

  $Super$$main();  //calls the original function
}

---

====
Here i have two questions.

1. Why a function name can be declared as $...$$....
Does it have any special meaning?

2. Why did it call "itself"? What does the original function mean here?

BTW, it's a code downloaded from ARM.com

Thanks a lot for the explanation.

To me it looks like there´s some sort of preprocessor which uses these keywords to do some things. The code itself is illegal C/C++ and won´t compile using standard C/C++ compilers.

It looks they are trying some inheritence stuff in plain C since the function is called SUB and the call inside is SUPER. But like GNiewerth said, this is non standard.

Some revision control systems have a substitution mechanism that replaces keywords of the form $...$ with other values. That doesn't explain the $$ though.

Maybe it´s Micro$oft specific ? :D

Probably CodeSnippets?
