我们从Python开源项目中，提取了以下5个代码示例，用于说明如何使用pty.STDERR_FILENO。
def do_execute(self, stdin_file, stdout_file, stderr_file, cgroup_file): pid = fork() if not pid: chdir('/in/package') if stdin_file: fd = os_open(stdin_file, O_RDONLY) dup2(fd, STDIN_FILENO) os_close(fd) if stdout_file: fd = os_open(stdout_file, O_WRONLY) dup2(fd, STDOUT_FILENO) os_close(fd) if stderr_file: fd = os_open(stderr_file, O_WRONLY) dup2(fd, STDERR_FILENO) os_close(fd) if cgroup_file: enter_cgroup(cgroup_file) execve(self.execute_file, self.execute_args, SPAWN_ENV) return wait_and_reap_zombies(pid)
def do_build(self, output_file, cgroup_file): pid = fork() if not pid: chdir('/out') os_close(STDIN_FILENO) if output_file: fd = os_open(output_file, O_WRONLY) dup2(fd, STDOUT_FILENO) dup2(fd, STDERR_FILENO) os_close(fd) if cgroup_file: enter_cgroup(cgroup_file) execve(self.compiler_file, self.compiler_args, SPAWN_ENV) return wait_and_reap_zombies(pid)
def __fork_pty(self): '''This implements a substitute for the forkpty system call. This should be more portable than the pty.fork() function. Specifically, this should work on Solaris.
