Interpretation Request #24
Topic: schedpolicy etc Relevant Clauses: 18.104.22.168
1) Clause 22.214.171.124, page 122 D10, lines 333-342
A default value for the schedpolicy attribute is not specified.
What is the default value for this attribute?
2) Clause 126.96.36.199, page 122 D10, lines 353-357 A default value for the schedparam attribute is not specified. What is the default value for this attribute?
Implementations are already providing different values (drastically) which will effect portability. Some implementations consider the default value to be NULL; others return an actual value for this attribute as the default value. This case is not merely different default values, but actual differences in what this attribute represents. This impacts portability. What is the default value/behavior of this attribute?
This is a duplicate. See Interpretation #3, part 5.
