When writing a C function that pushes a table onto the stack as its return value to the Lua caller, what should it return in the C context? I know you are supposed to return the number of values that you are passing back to the Lua caller, but in the case of a table, is it 1 for the table reference, or do you need to account for the contents of the table?
The method of passing back a table I am using is shown in " Pushing a Lua Table. "
You are only returning one lua value directly, so your C function should return 1.
Something like this:
int my_table( luaState * L) {
lua_newtable(L);
lua_pushstring(L, "a_key");
lua_pushstring(L, "a_value");
lua_settable(L, -3);
return 1;
}
