Re: Calling C functions from Lua Code

["Victor Bombi" <sonoro@...>]

Do you mean a lua_CFunction? Thats a function that has to be "exported" to 
lua with lua_register or similar
or you mean a regular C function?

for the first case you have the name in lua that can be used as 
function_name(1,2)
for the second case you need ffi that you can get with luajit or in plain 
lua with any ffi module.

Subject: Calling C functions from Lua Code


Hi All

I have a requirement as below.




1. From C code, call lua function ( I know how to do it)

2. While lua function is being executed,  call a C function

3. Lua function returns

4. C code completes and program terminates


Hope it should be possible.


Can somebody please help me how to implement above point 2 (how to call a C 
function from Lua).


Thanks

Austin
