aot_top_get_val Interface

public interface aot_top_get_val

Get the value on top of the Lua API stack

This is the most basic operation to retrieve a value. It is also most flexible in the sense, that it does not matter how the value actually gets on top of the stack by previous Lua operations.

The interface looks like this: call aot_top_get_val(val, errCode, L, default). See for example aot_top_get_real for a more detailed description of the parameters.

aot_top_get_val can not be in the same generic interface as the other aot_get_val routines, as it results in ambiguities of the interfaces.
