Quick examples:
local ffi = require "ffi"
local reflect = require "reflect"
ffi.cdef 'int sc(const char*, const char*) __asm__("strcmp");'
print(reflect.typeof(ffi.C.sc).sym_name) --> "strcmp"
for refct in reflect.typeof"int(*)(int x, int y)".element_type:arguments() do
print(refct.name)
end --> x, y
t = {}
assert(reflect.getmetatable(ffi.metatype("struct {}", t)) == t)For the full API reference, see http://corsix.github.io/ffi-reflect/.
