Status
The Status enum wrap's the posix exit status.
The Result struct encapsulates the result of waiting for a process state change.
CORE_POSIX_DLL_PUBLIC std::ostream & cerr() noexcept(true)
Access this process's stderr.

CORE_POSIX_DLL_PUBLIC ChildProcess fork(const std::function< posix::exit::Status()> &main, const StandardStream &flags)
fork forks a new process and executes the provided main function in the newly forked process.
The Process class models a child process of this process.
CORE_POSIX_DLL_PUBLIC std::istream & cin() noexcept(true)
Access this process's stdin.
CORE_POSIX_DLL_PUBLIC std::ostream & cout() noexcept(true)
Access this process's stdout.
The Process class models a process and possible operations on it.
CORE_POSIX_DLL_PUBLIC ForkAndRunResult fork_and_run(const std::function< core::posix::exit::Status()> &service, const std::function< core::posix::exit::Status()> &client)
Forks two processes for both the service and the client.
Flags
Flags enumerates different behavior when waiting for a child process to change state.
