How to learn linux system programming by reading man pages?

Question

I read man creat, man open and man close & i find man pages the best source to learn linux.

But i need a read map, i want to know a list of man pages that gives the high level overview and then subsections that dive into the details.

Please advise.

Answer 1

So man -k intro gives a list including the following:

intro (1)            - introduction to user commands
intro (2)            - introduction to system calls
intro (3)            - introduction to library functions
intro (4)            - introduction to special files
intro (5)            - introduction to file formats and filesystems
intro (6)            - introduction to games
intro (7)            - introduction to overview and miscellany section
intro (8)            - introduction to administration and privileged commands

Each one can be read by man intro.N (N being 1-8), these intro pages looks like the begining of chapters in the man documentation.
