Treating function calls and function prototypes distinctly

In C  I have a use case where I want to find a function's definition, but
if one does not exist i want to find the function's prototype (aka
declaration). At present, if I don't have a definition I cycle thru all
call and prototype declarations, but not in any particular order. How can I
restrict my search to just function prototypes?

Thanks.
