For the standards columns, the cells are blank to indicate not required or "INCL" to indicate required. For the RTEMS colums, the following values are used: CTS-YES - FACE Conformance Test Suite reports present CTS-NO - FACE Conformance Test Suite reports not present RT-YES - RTEMS specific probe test reports present RT-NO - RTEMS specific probe test reports not present HAND-YES - Override by hand to indicate RTEMS supports this The "RTEMS Impl Notes" column has the following values: + ENOSYS to indicate the method is a stub that sets errno to ENOSYS and returns -1 + SUSP to indicate the method is limited due to the Single Use, Single Process nature of RTEMS.
