POSIX Application Environment Profiles (AEP)

Although inactive, IEEE 1003.13-2003 defined a number of AEP that inspired the modern subprofiling options of IEEE 1003.1-2017. The single-purpose realtime system profiles are listed below, for reference, in terms that agree with the current POSIX-1 standard. PSE54 is not considered at this time.

System Interfaces

The required POSIX System Interfaces are supported for each Application Environment Profile.
