writing libraries

[Novak Elliott]

i need a few pointers for writing static (.a) and dynamic link libraries
(.so). I saw once in a makefile the command "ar myfile.c ..." to build a
static library ie mylib.a . Either a reference book, URL (prefereble) or a
concise description of how i would
        - compile a static library
        - compile a dynamic library
        - build a c program with a static library
        - build a c program that links with a dynamic lirary at run time
thanx in advance,
Novak.
