The ismarked function in Julia determines if a given stream s is marked or not. It returns true if the stream is marked.
julia> io = IOBuffer("Hello, world!");
julia> mark(io);
julia> ismarked(io)
trueIn this example, the ismarked function is used to check if the stream io is marked.
Please note that the mark function is used to mark a stream, the unmark function is used to unmark a stream, and the reset function is used to reset a stream to the marked position.
julia> io = IOBuffer("Hello, world!");
julia> mark(io);
julia> ismarked(io)
true
julia> unmark(io);
julia> ismarked(io)
false
julia> reset(io);
julia> ismarked(io)
trueThese functions are useful when working with streams in Julia, allowing you to mark positions and perform operations based on the marked position.
