process configuration and status Create a new zproc. NOTE: On Windows and with libzmq3 and libzmq2 this function returns NULL. Code needs to be ported there. Destroy zproc, wait until process ends. Return command line arguments (the first item is the executable) or NULL if not set. Setup the command line arguments, the first item must be an (absolute) filename to run. Setup the command line arguments, the first item must be an (absolute) filename to run. Variadic function, must be NULL terminated. Setup the environment variables for the process. Connects process stdin with a readable ('>', connect) zeromq socket. If socket argument is NULL, zproc creates own managed pair of inproc sockets. The writable one is then accessbile via zproc_stdin method. Connects process stdout with a writable ('@', bind) zeromq socket. If socket argument is NULL, zproc creates own managed pair of inproc sockets. The readable one is then accessbile via zproc_stdout method. Connects process stderr with a writable ('@', bind) zeromq socket. If socket argument is NULL, zproc creates own managed pair of inproc sockets. The readable one is then accessbile via zproc_stderr method. Return subprocess stdin writable socket. NULL for not initialized or external sockets. Return subprocess stdout readable socket. NULL for not initialized or external sockets. Return subprocess stderr readable socket. NULL for not initialized or external sockets. Starts the process, return just before execve/CreateProcess. process exit code PID of the process return true if process is running, false if not yet started or finished The timeout should be zero or greater, or -1 to wait indefinitely. wait or poll process status, return return code send SIGTERM signal to the subprocess, wait for grace period and eventually send SIGKILL return internal actor, useful for the polling if process died send a signal to the subprocess set verbose mode
