Re: for a specific glibc version, how could I get the functions declared in head file are implementation in which library?

there is only one library, the C library, and gcc automatically does
"-lc" for you.
 Well, sinf() for example needs -lm while clock_settime() -- -lrt.  I
suppose the right place for such information are the glibc info pages, but
there is never enough force available onboard to put all the bits there.
There might be a book available on the market as well, but I have never
bothered checking that.  Failing those, `objdump' on the libraries in
question will reveal which symbols they provide.

the respective man pages from the linux-man-pages project already documents things nicely.

Indeed -- you beat me to the punch pointing that out Mike.


Maciej, if you find that a particular page in man-pages (http://www.kernel.org/doc/man-pages/online_pages.html) fails to provide that info, let me know.

Cheers,

Michael
