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

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.
