在何处查找管道信息？ [英] Where to Find Pipe Information?

问题描述

在Linux平台上，我需要从

PHP脚本中调用已编译的C程序（到做一些特殊的身份验证），并保持从PHP脚本传递给编译的C程序秘密的信息，即

信息不应传递在命令行上。


我建议使用PHP管道操作函数（例如popen）。


我在哪里可以找到更多关于管道的信息，特别是：


a）如何使用C库调用来操作管道？


b）Linux API（在C下面）库）？


我需要足够的信息来编写已编译的C程序，通过管道与PHP脚本交换

信息，以及处理异常

条件。


我只是不确定在哪里看...我甚至不确定C库是否

记录了......以及哪个文件n是合适的。


谢谢。

Hi,

On a Linux platform, I have the need to call a compiled ''C'' program from a
PHP script (to do some special authentication), and to keep the information
passed from the PHP script to the compiled ''C'' program secret, i.e. the
information should not be passed on the command-line.

The PHP pipe manipulation functions (such as popen) were suggested to me.

Where can I find out more about pipes, specifically:

a)How to use the C library calls to manipulate pipes?

b)The Linux API (below the C library)?

I need enough information to write the compiled ''C'' program, to exchange
information with the PHP scripts via pipes, and to handle exception
conditions.

I''m just not sure where to look ... I''m not even sure if the C library is
documented ... and which documentation is appropriate.

Thanks.

我不知道Linux资源，但你试过PHP.net吗？

I don''t know Linux resources but have you tried PHP.net?

我想我不明白传球的问题它在命令

处理错误而不会挂起有时会很棘手。

I guess I don''t understand the problem with passing it in the command
line. If it''s a process-to-process communication, it won''t be visible
anyway.

As for using pipes - if you''ve never used them before, you''re going to
need to do a fair amount of reading. The api''s aren''t complicated, but
handling errors without hanging can sometimes be tricky.

PHP管道操作我建议使用各种功能（如popen）。

Google" stdio.h"。要从stdin读取，你就可以这样做，就像从键盘读取
一样，使用gets（）和getc（）等函数。要用
写入stdout，你可以使用puts（）或printf（）。


如果你已经有了一个工作程序，你很可能只需要管道

将数据输入其中并将其取出。

Google "stdio.h". To read from stdin, you just do it as though you''re
reading from the keyboard, with functions like gets() and getc(). To
write to stdout, you use puts() or printf().

If you have a working program already, chances are you can just pipe
data into it and get stuff back out.
