Re: [Bug-wget] Calling wget programmatically from C/C++ code

[Chitra Nanda]

Hi Micah,

I want the same piece of code to work on vmware environment in addition to
all the other platforms.
In vmware Hypervisor environment there is no support for system(), so I will
not be able to use the same.
Well I am not keen on processing the output till wget finishes the download.
In my application I can process the file
only after the entire file download is complete. Using apis of wget I will
be forcing a hard dependency on wget for file
downloading. I need to do it programmatically only if wget is available on
the system I am trying to do the download.

Can you please suggest any pointers on writing the interface, I have never
done it anytime.
If you can suggest some pointers on the same, it will be great. All I need
to do is to
download a file using http from another remote machine. That is all.

You have mentioned that there is no portable way to use functions of wget.
Is there any platform specific way to do that. If you can suggest ways to do
on
one platform also it will be great. If you can suggest a way of doing it on
Linux,
it will help.

Thanks for your time and help.

Thanks and Regards,
Aruna
