Detailed Description

Lua sandbox serialization.

Definition in file luasandbox_serialize.h.

Function Documentation

LSB_EXPORT void lsb_add_serialize_function	(	lua_State *	lua,
		lua_CFunction	fp
	)

Add a serialization function to the environment table.

The environment table must be on the top of the stack. This function will receive the userdata, fully qualified variable name, and lsb_output_buffer struct as pointers on the Lua stack.

lsb_output_buffer* output = (output_data*)lua_touserdata(lua, -1); const char key = (const char)lua_touserdata(lua, -2); ud_object* ud = (ud_object*)lua_touserdata(lua, -3);

Parameters

lua	Pointer the Lua state.
fp	Function pointer to the serializer.

Returns

lsb_err_value NULL on success error message on failure

LSB_EXPORT lsb_err_value lsb_serialize_binary	(	lsb_output_buffer *	output,
		const void *	src,
		size_t	len
	)

Serializes a binary data to a Lua string.

Parameters

output	Pointer the output buffer.
src	Pointer to the binary data.
len	Length in bytes of the data to output.

Returns

lsb_err_value NULL on success error message on failure

LSB_EXPORT lsb_err_value lsb_serialize_double	(	lsb_output_buffer *	output,
		double	d
	)

More efficient serialization of a double to a string.

Parameters

output	Pointer the output buffer.
d	Double value to convert to a string.

Returns

lsb_err_value NULL on success error message on failure
