Interpretation Request #31
Topic:exit should not invoke cancellation cleanup handlers or per-thread data destructors Relevant Sections: XSH exit
"exit()" should behave the same as _exit() or _Exit() with respect to cancellation cleanup handlers and per-thread data destructors. Replace Threads terminated by a call to _Exit() or _exit() shall not invoke their cancellation cleanup handlers or per-thread data destructors. with Termination of a process shall not invoke any thread cancellation cleanup handlers or per-thread data destructors.
The standards states the requirements for exit(), and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor.
Rationale for Interpretation
Notes to the Editor (not part of this interpretation)
exit() should be described on a separate page that explains at the end that exit() inherits the behavior described separately for _exit()
