E. Subprofiling Considerations (Informative)
This section contains further information to satisfy the requirement that the project scope enable subprofiling of POSIX.1-2017.
The approach taken is to include a general requirement in normative text regarding subprofiling and to include an informative
section (here) containing a proposed set of subprofiling options.
E.1 Subprofiling Option Groups
The following Option Groups1 are defined to support profiling. Systems
claiming support to POSIX.1-2017 need not implement these options apart from the requirements stated in XBD POSIX Conformance. These Option Groups allow profiles to subset the System
Interfaces volume of POSIX.1-2017 by collecting sets of related functions.
