* @arg out stdout of the program, to be read from. If NULL then not redirected
* @arg program full path of the program, without reference to $PATH
* @arg argv NULL terminated array of strings, program arguments (includiong program name)
* @arg envp NULL terminated array of environment variables, NULL => preserve environment
