    programming in c on unix

    I have come across this term used by a lot of companies which post their vacancies that the candidate must be " proficient programming c on unix". What does that imply .... I mean i program on c using visual studio and i suppose the syntax rules dont change if i use any other OS. I know that the compilation is a bit different on the linux platform like using the gcc command for compilation and all that stuff. Is there any other difference which is implied by this term ????????

    Some of the header files are different, as are some of the function calls into the system. The differences would be akin to a unix programmer considering coding on Windows, and having to learn all the Windows specific crap that you (I suppose) are pretty familiar with.

    You don't get WinAPI, and get POSIX functions instead. For GUI, you'll need to use another library (or not, if you already use a portable one) - WxWidgets, Qt, GTK... many choices. Most of them are cross-platform (runs on Windows), too.

    POSIX

    If i am not wrong then POSIX standard allows multithreading in c which i suppose is lacking on windows platform....

    POSIX includes a lot of things. It's like WinAPI. POSIX Threads (pthread) is just a part of it.

    Windows doesn't allow multithreading? Well that's certainly news to me. Did they stop supporting multithreading in Windows 7 or something?

    Windows do allow multithreading, but not following the POSIX standard
