Greetings.
new_fluid_synth() returns a fluid_synth_t*, presumably so that
the process can run multiple simultaneous synths presumably with
different settings. But how common are multiple synths in practice ?
(
Background: I'm maintaining a Lua module:
http://www.pjb.com.au/comp/lua/fluidsynth.html
http://luarocks.org/modules/peterbillam
in which the C returns the fluid_synth_t* back into Lua (as an integer,
currently) so that the app can run multiple synths. This has some
drawbacks, including being a security weakness, also if the size of
int is different from (especially less than!) the size of pointer.
There are a number of solutions, but the simplest is to allow just
one synth at once and keep its fluid_synth_t* in a static C variable.
( I could also keep a C-array of synths; or return the fluid_synth_t*
as 'userdata' PiL p.194 and associated 'metatable' PiL p.197,
which is the classy solution, but not so simple... )
