Some general rules for the scope of POSIX processes follow, as
illustrated in Figure 1:
- POSIX semantics applied to a POSIX process from outside the POSIX process (interprocess semantics) are applied to a Language Environment process. For example, a signal directed from a process to another process using kill is applied to a Language Environment process.
- POSIX semantics scoped to within the current POSIX process (intraprocess semantics) apply to the current Language Environment enclave. For example, heap storage is recognized throughout an enclave.
