I hope, your .c file includes your .h file.
Then do this:
gcc -fPIC -c prog.c
gcc -shared -o libprog.so prog.o -lc
(You can put in a soname, too)

To link another prog with your lib:
gcc -o newprog newprog.c -L. -lprog
To execute newprog, you should add the path of the shared lib to
the LD_LIBRARY_PATH environment variable:
setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:.
or 
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:.
or something similar your shell understands.

Hope that helps,
Martin.
