Checking stdin for new data

[MrUmunhum]

Hi group,

I'm looking for a way to check if any data is waiting on stdin.
I know I can use Select under linux but that will not work with
Windozes and I want to be able to use the same code for both.
I could use getc and then ungetc but that is sloppy.

Any ideas?

may we ask what language?

Hi,
How about setting up buffers and then you can read write manipulate them as you wish. Use a general buffer setup in C etc so that it is portable.

I am using standard C.

That is what I am doing but it gets a little messy. The problem is that I am waiting for input in subroutine and the input can be either a numerical string for the length of the data or the data itself. It work well but the caller may send more data then they sead they were. in this case I need to filter out the extra data, reading the steam until I get what looks like a valid length ( "nn\n") or a quit command ("q\n").

It would just be clearer to have a way of checking the input.

I know nothing about programming under Windows, but:
select Function (Windows)

select() is probably the best option for this if you can get it working, since it's explicit purpose is to tell you when a stream is ready.

Windozes only supports Select for scokets not other file types.
