That number gives the number of stack slots used by arguments.
Which implies, it can only be found if the declaration is correct.
A correct declaration would be:
ffi.cdef[[
// <-- Add definitions for apr_* types here.
apr_status_t __stdcall apr_env_get(char **value, const char *envvar, apr_pool_t
*pool);
]]
local apr = ffi.load("...") -- <-- Use the DLL name here
print(apr.apr_env_get) -- Ought to print cdata<...>
--Mike
