No, select knows nothing about Net::SSLeay nor its buffers. select, being an interface to a low-level (kernel) routine (select(2)) only knows about buffers inside of the operating system.

IO::Socket::SSL notes of start_SSL():

This will convert a glob reference or a socket that you provide to an IO::Socket::SSL object.
so you are lucky that select even works at all.

Perhaps IO::Socket::SSL could use some support for "asking if there is any data left inside of its buffers". Then you can loop until there is no data left in the buffers inside of the loop that uses select.

But that assumes that asking for 200 bytes when there are only, for example, 100 bytes in the buffer doesn't hang waiting for the next 100 bytes to arrive.

But it looks like IO::Socket::SSL supports non-blocking reads, so you should be able to get something working.

Update: Ah, pending(); I missed that. Well spotted, rowdog. That makes for a nice solution.
