This is what I see in the example from mailine docs:
/**
* foobar() - Brief description of foobar.
* @argument1: Description of parameter argument1 of foobar.
* @argument2: Description of parameter argument2 of foobar.
*
* Longer description of foobar.
*
* Return: Description of return value of foobar.
*/
int foobar(int argument1, char *argument2)
What are you referring to?
