lua_cpcall — calls
the C function in protected mode, function indicator [-0, + (0|1),
-]
#include

lua_cpcall(lua_State
*L, lua_CFunction
func, void
*ud);
lua_cpcall()
calls the C function func in protected mode.
func starts with only one element in its stack, a
light userdata containing ud.
In case of errors, lua_cpcall() returns
the same error codes as lua_pcall(3), plus the error
object on the top of the stack; otherwise, it returns zero, and does not
change the stack. All values returned by func are
discarded.
