get_top_logical_v Subroutine

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

Arguments

Type IntentOptional Attributes Name
logical, intent(out) :: val(:)

Vector read from the Lua table.
integer, intent(out) :: ErrCode(:)

Error code describing problems encountered in each of the components. This array has to have the same length as val.
type(flu_State) :: L

Handle to the lua script
logical, intent(in), optional :: default(:)

A default vector to use, if no proper definition is found. Components will be filled with the help of this default definition.
