Tcl/Tk GUI and pthread

I have a Tcl/Tk GUI.

The GUI needs to be able to accept updates to entry boxes once a second
from a pthread running in a C library.

Any pointers on how to get started with this? I tried Tcl_SetVar(), then
calling an update back in the Tcl/Tk code, but I'm missing too many
updates. Sometimes, as long as 30 seconds between updates appearing in the
entry box on the GUI.

Thanks,
Randy

Maybe I am missing something, but an entry is primarily intended for user
input - why do you need to update it once a second? Are you sure it is an
entry you should be updating?

I sure hope there is not much more than one or maybe at most two
characters in that entry box - because otherwise, by the time someone
tries to type something in the entry box, your pthread once a second update
will have reset it to whatever value it has been using...
