c++ Copy file \ Generic implementation

Question

I'm looking for a good C++ copy function that encapsulate inside local copy, UNC copy, and HTTP download copy. something like

bool copy(string path1, string path2) {}

I'm not strong at c++ and have tendency to create memory leaks more than are needed. Is there a complete implementation out there?

Thanks!

Answer 1

Basically you are asking someone to implement a generic copy function that is able to take various different URI's?

For example, if you want to do HTTP downloads you will need a library that knows HTTP, such as cURL.

The other two, (local path and UNC) should work on Windows, look at using fstream . There are plenty of examples.

As it stands this question is extremely vague and isn't really requesting help; merely asking us to implement what sounds like homework.

Answer 2

您可能需要研究libcurl 。

Answer 3

The copying is easy:

destination << source.rdbuf();

Writing the streambuf to handles the different sources and destinations is less obvious, although if you have a good library which handles all of the dirty work, it shouldn't be too hard to wrap it in a streambuf . (Otherwise: a robust implementation of any socket protocol is not something for someone not strong at C++.)
