Setting source IP with posix sockets

Is it possible for an application to request a socket (tcp) and have it set the source address without using raw sockets? (the addresses would be bound to the interfaces. [no spoofing]).
This would be a tcp client connection, not bind()ing to a specified address.

Can Win32 message loops survive being ported to native linux?

I would like to port a large Win32 DLL to native linux in C++. I don’t think I can use Wine for a DLL like mine, because users of the DLL would then also have to be in Wine, and then they would all whine… As a Windows C++ programmer, I don’t (yet) have any familiarity with the GUI front-end services in linux, but if it logically runs on anything like win32 message loops, fonts, bitmaps, invalidation regions, getmessage( ) calls and so forth, it should be a fairly straight forward remapping of my existing code.

How is the Linux repository administrated?

I am amazed by the Linux project and I would like to learn how they administrate the code, given the huge number of developers. I found the Linux repository on GitHub, but I do not understand how it is administrated. For example the following commit: https://github.com/torvalds/linux/commit/31fd84b95eb211d5db460a1dda85e004800a7b52

How to develop a menu for Linux apps [closed]

It’s difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 12 years ago. I want to create a python panel for […]

Which language is more suitable heavy file tasks?

I need to write a script (based on basic functions) to process /image/audio/video files. The process is mainly filesystem tasks and converts. The database of files has been stored by mysql. The script is simple but cause heavy tasks on the system; for example renaming/converting/copying thousands of file in a run. The script does not read the content of files into memory, it just manage the commands for sub-processes. The main weight is on the communication with filesystem. The script will be used regularly for new files. My concern is about performance. I am thinking of

unseen/unknown function definition in linux source

Can any one please explain this piece of code I found in the linux kernel source. I see a lots of code like this in linux and minix kernel but dont seem to find what it does (even if C compilers support that kind of function definition)

What is the lifecycle for loading a Linux Desktop Environment?

I’m looking into delving into a bit of custom OS work (and yes I understand that doing any development at the DE level or lower on an OS is extremely complex and not a light thing to undertake, curiosity is driving this though), I’m in the research phase right now, digging around and learning by example from the source code for projects like GNOME, KDE and XFCE.
