From iOS programming to Linux system programming
Hello.
I like Linux and C programming language. Allways wanted to understand kernel and become a Linux system programmer. And I also like Objective-C and iOS. These two programming areas have relations:
1. Linux and iOS are UNIX-like systems, POSIX compliant.
2. It is useful to know C language for iOS programmer.
And I have these questions:
1) Is it useful for usual iOS web/GUI/game programmer to know UNIX/FreeBSD programming?
2) Is it useful for usual iOS web/GUI/game programmer to know iOS kernel and iOS system programming?
3) Is it difficult to transit from iOS programming to Linux system programming?
