Function sunvox_sys::sv_open_slot

pub unsafe extern "C" fn sv_open_slot(slot: c_int) -> c_int

Opens a slot.

A slot is like an instance of the SunVox engine. Each slot can have a single project loaded at a time. The library supports up to four slots, 0 to 3 inclusive. This call appears to hang if called with a number outside this range.

Returns 0 on success, -1 on failure. Failure conditions include the slot already being open.

I say "like" an instance of the engine because I think all slots share the same tick counter, which you can get by calling sv_get_ticks().
