aot_top_get_long Subroutine

private subroutine aot_top_get_long(val, ErrCode, L, default)

Interpret topmost entry on Lua stack as a single precision real.

Arguments

Type IntentOptional Attributes Name
integer(kind=long_k), intent(out) :: val

Value of the Variable in the script
integer, intent(out) :: ErrCode

Error code to indicate what kind of problem might have occured.
type(flu_State) :: L

Handle to the Lua script
integer(kind=long_k), intent(in), optional :: default

Some default value, that should be used, if the variable is not set in the Lua script.
