Re: Poping C function arguments from the Lua stack

[Meir Shpilraien <meir@...>]

I meant that the Lua stack size is limited by LUAI_MAXCSTACK to 8k. I want to pop the arguments out of the Lua stack so I will have empty slots to work with.

Why do you have 8k stack limit? (what system do you use? usually in
"normal CPU systems" like PC the stack size will be more in Megabyte
range?)

I am asking because users might send a lot of arguments to the C function (using unpack for example) and acquire all the room on the stack (which is set by default to 8K), leaving no place to push replies or perform other operations that require the stack.
