I haven't written much in any real programming language but since I studied java in my course it has given me a better understanding of objects, classes and methods, not that C uses all of those but the underlying concepts are similar, not to mention syntax, since C is mother of most modern languages.
Here is something I threw together just to get a better handle on things (I can hear them now.. should he be fixing woof?
).This is about the first fully functional app I've written from the ground up. It is just a simple program to get kernel major, minor, sub, sub-sub versions and extra version info that some kernel builders tack onto the end. It supports 2 and 3 series kernels. There are probably bugs and bloat in it, though hopefully I've removed most of that. It can be compiled normally with gcc using shared libs or statically with musl (and probably uclibc, dietlibc etc).
Oh and before anyone says.. "oh but I can do that in one line of shell!".. er, so can I.. (yes it's over 200 lines
)Attached is the source with configure script too, no it doesn't use automake or anything! It's just easy to add options, (like --enable-static if you have musl. makes 26k bin, upx'd >> 17k bin).
Thanks to Karl Godt for testing and advice.
Tested on slacko, dpups wheezy and sqzd (2.6 kernel) and slackware 32 and 64.

v0.5 added sys/utsname.h dependency, surprisingly makes static musl build smaller! ..gcc build about the same. system() calls add bloat it seems.
v0.6 removed kernel_min function, kernel_sub fucntion along with dotnum handles it all. Changed dotnum from int to void, changed kernel_sub to accept param based on which option calls it. reworked algorithms to be more robust.
) plus there are extra dots and all sorts of crap. I just tried the musl static version actually..
