The synopsis of the prctl.2 page has:
int prctl(int option, ...
This makes no sense, because
- the first argument is not optional; it is mandatory.
- the title of the page is "operations on a process or thread".
It is thus clear that the first argument indicates the operation to perform.
Find attached the correction.
