Addresses UK-188 [CD1]

The function _Exit does not appear to be defined in this standard. Should it be added to the table of functions included-by-reference to the C standard?

[ 2009-05-09 Alisdair fixed some minor issues in the wording. ]

[ Batavia (2009-05): ]

We agree with the proposed resolution. Move to Tentatively Ready.

Proposed resolution:

Add to 17.5 [support.start.term] Table 20 (Header <cstdlib> synopsis) Functions:

_Exit

Add before the description of abort(void):

void _Exit [[noreturn]] (int status)

The function _Exit(int status) has additional behavior in this International Standard:

• The program is terminated without executing destructors for objects of automatic, thread, or static storage duration and without calling the functions passed to atexit() (6.9.3.4 [basic.start.term]).
