Text Formatting ⇒ Get current Cursor Position

[EmilioLazo]

Hi

What procedure can be used to ask TeX for the current cursor position in the page?

What I'm doing? I have a textblock* environment with some text and one image. By how textblock works, when the environment ends (like picture environment), its box is 0 vertical size or something similar resulting in overlapping newly written text after ending this environment.

Would be very useful getting the current position before closing textblock* and saving it into a variable, length, counter or whatever that can be readed just after \end{textblock} to move there, or to leave the vertical space needed to avoid text overlapping.

Any idea?
Thanks!
