No, the generic programming capabilities of C are very limited.
But you have some options. Follow your idea with the #include
"function.c",
but if you do not want to include a file twice, copy in with an other
name,
this fits well in a Makefile.
<off>
If you accept a program with several object files, why don't you
create
a source file with this expand function, where the type name is a
macro.
Then in the makefile you compile this expand.c as
expand1.o: expand.c type1.h expand.h
cc -E -Dtype=type1 -c expand.c
expand2.o: expand.c type.h expand.h
cc -E -Dtype=type2 -c expand.c
</off>
Your source generator can be the combination of the preprocessor and
make.
