The file in which the wrapping is defined is .../src/g-wrap/gnc.gwp
If you look in it, you'll find that these are, respectively, mapped
to:
a) (gnc:account-get-split account index)
b) (gnc:account-get-split-list account)
c) (gnc:account-get-split-count account)
They are reasonably good examples of how to wrap C functions, as they
have a diverse set of arguments/return values. It would be a good
move to change the documentation strings to something more useful than
the present "Undocumented."
Note that a documentation file, gnc.html gets "compiled" out of the
data in gnc.gwp, and is also well worth looking at.
