lua — control - in-kernel Lua states

-
-
-

-

lua*

-

-
- #include <sys/types.h> -
- #include <sys/lua.h>

-
-
-

-

The lua device allows to create, control, - and delete Lua states in the kernel through an ioctl(2) - interface. Moreover, lua can be used to load Lua - scripts into a Lua state and to assign modules to an existing state, i.e. - perform the equivalent of the Lua command require. - lua is also used to retrieve information about - currently active Lua states.

-
-
-

-

Lua modules are used to provide functionality to Lua scripts not - available in the language itself, e.g. to access core kernel functionality - like printing text on the console. Unlike in user space Lua, where Lua - modules are files in the filesystem, modules must be provided to - lua in the form of loadable kernel modules that - register their functionality with lua. Modules are - loaded using the require Lua command; whether this - command is available or not is controlled by a sysctl(8) - variable. lua by default tries to load a kernel - module named - - when it encounters the Lua command require 'foo'.

-
-
-

-

The operation of lua can be controlled by - means of the following sysctl(8) variables:

-
-
-
When set to 1, lua tries to autoload kernel - modules. -

The default value is 1.

-
-
-
When set to 1, loading of Lua bytecode is allowed. -

The default value is 0.

-
-
-
When set to a value > 0, lua limits the number - of instructions executed to this number. -

The default value is 0.

-
-
-
When set to 1, enables the require command in Lua. -

The default value is 1.

-
-
-
When set to a value > 0, verbosity is increased. -

The default value is 0.

-
-
-
-
-

-

The following structures and constants are defined in the - <sys/lua.h> header file:

-

-
-
-
Returns information about the lua states in the - lua_info structure: -
- 
#define MAX_LUA_NAME		16
-#define MAX_LUA_DESC		64
-
-struct lua_state_info {
-	char	name[MAX_LUA_NAME];
-	char	desc[MAX_LUA_DESC];
-	bool	user;
-};
-
-struct lua_info {
-	int num_states;		/* total number of Lua states */
-	struct lua_state_info *states;
-};
-
-

-
-
-
Create a new named Lua state with name and description in the - lua_create structure: -
- 
struct lua_create {
-	char	name[MAX_LUA_NAME];
-	char	desc[MAX_LUA_DESC];
-};
-
-

-
-
-
Destroy a named Lua state. -

-
-
-
Perform the equivalent of the Lua command require in a - named state. The name of the state and of the module name is passed in the - lua_require structure: -
- 
#define LUA_MAX_MODNAME		32
-
-struct lua_require {
-	char	state[MAX_LUA_NAME];
-	char	module[LUA_MAX_MODNAME];
-};
-
-

-
-
-
Load Lua code from the filesystem into a named Lua state. The name of the - state and the path to the Lua code are passed in the - lua_load structure: -
- 
struct lua_load {
-	char	state[MAX_LUA_NAME];
-	char	path[MAXPATHLEN];
-};
-
-

The path element of the lua_load - structure must contain at least one ‘/’ character.

-
Lua device file.

-

-

ioctl(2), luactl(8)

-
-
-

-

The lua device first appeared in - NetBSD 7.0.

-
-
-

-

The lua driver was written by - Marc Balmer - <mbalmer@NetBSD.org>.

-
-
-

-

The lua device is experimental. - Incompatible changes might be made in the future.
