Interpretation Request #106
Topic:
reinitializing an initialized spawn attributes object Relevant Sections: 3.1.5.2 PASC

1003.1d, Section 3.1.5.2 is not clear whether its permissible to reinitialize an already initialized spawn attributes object. It would seem clear from the presence of the destroy operation that such an action should result in undefined behavior but needs stating here.

Add "The effect of initializing an already initialized spawn attributes object is undefined" (after d14,p18,l175)

Interpretation Response
The standard does not speak to this issue, and as such no conformance distinction can be made between alternative implementations based on this. This is being referred to the sponsor.

Rationale for Interpretation
This is an unaddressed issue, its recommended this be addressed in the 1003.1 revision.

Notes to Project Editor (not part of this interpretation)
Apply the solution noted in section 11 for the 1003.1 revision. Forwarded to Interpretations group: 21 May 2000 Proposed resolution: 28 May 2000 Finalized Interpretation: 25 July 2000
