如何在C中将缓冲区数据写入PDF文件 [英] How to write buffer data into PDF file in C

问题描述

你好，

我在AIX上用纯C语言编写代码.
我想读取PDF文件并将数据存储在缓冲区中.
然后从该缓冲区中将其写入另一个PDF文件.
PDF文件有任何功能.
我用了fputs(buffer，fileptr);
但是它以不同的格式写入数据.

如何从PDF读取数据并将其写入另一个PDF文件.

请帮帮我.
在此先感谢.

不，这不对.数据将完全按照所提供的进行写入.如果您的文件不再是有效的PDF，则您的代码已损坏.如果您只是要进行复制，是否可以访问标准C之上可能提供文件复制例程的任何特定于平台的库?

No, it''s not. The data is written exactly as it''s provided. If your file is no longer a valid PDF, then your code is broken. If you''re just making a copy, do you have access to any sort of platform specific libraries above standard C that might offer a file copy routine ?

感谢回复.

我想从数据库服务器复制该PDF文档，并将其存储到AIX服务器上.

Thanks for reply.

I want to copy that PDF document from DB server and store it on to AIX server.

PDF文件以专有格式构造(可以从Adobe网站获取规范)，并且不是简单的文本文件.要将这样的文件从一个位置复制到另一个位置，应使用fread()和fwrite().

PDF files are structured in a proprietary format (you can get the specification from the Adobe website) and are not simple text files. To copy such a file from one location to another you should use fread()and fwrite().
