Swoole\Process::close — Close the pipe to the child process.
Swoole\Process::__construct — Construct a process.
Swoole\Process::daemon — Change the process to be a daemon process.
Swoole\Process::__destruct — Destory the process.
Swoole\Process::exec — Execute system commands.
Swoole\Process::exit — Stop the child processes.
Swoole\Process::freeQueue — Destroy the message queue created by swoole_process::useQueue.
Swoole\Process::kill — Send signal to the child process.
Swoole\Process::name — Set name of the process.
Swoole\Process::pop — Read and pop data from the message queue.
Swoole\Process::push — Write and push data into the message queue.
Swoole\Process::read — Read data sending to the process.
Swoole\Process::signal — Send signal to the child processes.
Swoole\Process::start — Start the process.
Swoole\Process::statQueue — Get the stats of the message queue used as the communication method between processes.
Swoole\Process::useQueue — Create a message queue as the communication method between the parent process and child processes.
Swoole\Process::wait — Wait for the events of child processes.
