Hello again,
I have a C library which has functions that print to stdout, sometimes
filling several screens. I would like to somehow redirect this output
temporarily to whatever is in the PAGER env. var. After the PAGER
quits, then regular interactive guile output should continue to go to
stdout.
Is it possible?
-Brett.

It's possible. What you would do is, dup stdout, open a pipe to less,
dup2 it to stdout, wait for less to exit, dup2 the old stdout back.
The default output port for Guile doesn't necessarily have to be stdout,
by the way.
