How peek at tcp socket data w/o reading it

[Kiniger, Karl (GE Healthcare)]

Hi,

hack wanted:

is it possible to peek a few bytes from a tcp socket which is
ready to read without actually reading the data? (or some
means to push already read data back similar to ungetc)

Any creative ideas welcome.

Karl
