The lua_module structure is declared as follows:
struct lua_module { char mod_name[LUA_MAX_MODNAME]; lua_CFunction open; int refcount; LIST_ENTRY(lua_module) mod_next; };
The mod_name defines the unique name of a module. A C function must use the standard Lua protocol in order to communicate with Lua, this part is maintained with the open element in the standard Lua way. refcount protects the module from being unloaded whilst still in use. The last parameter, mod_next, is used for the standard container LIST(3).
The klua_mod_register
() function registers
a new function which is made available to the
lua(9) device and Lua code using
the require
directive. The
require
directive can be called from
luactl(8) and the kernel Lua
version. The name parameter is a unique identifier of
the kernel Lua module. open points to a function used
in the C to Lua binding, defined with the appropriate standard Lua API.
Once registered, a C function can be unregistered with the
klua_mod_unregister
() function. This function takes
as its parameter the unique literal identifier of the extending module.
