This seems like such a useful function, I can't believe that someone
somewhere hasn't developed such a beastie (or at least something like
it).
I need source for a C function which, when called, sets up a pipe from
stdout into a pager (more, less, etc.). I would also like this to be
"undoable". That is, I want to be able to make the pager terminate
and redirect the output to return to regular old stdout mode. Something
like the following would be a typical invokation:
printf("this is on stdout.\n");
printf("this is on stdout too.\n");
printf("this is on stdout three :-).\n");
pager(); /* Now send stuff through a pager */
printf("this goes into the pager\n");
printf("another line into the pager\n");
printf("still another line into the pager\n");
printf("yet another line into the pager\n");
printf("this is the last line into the pager\n");
end_pager(); /* Done using the pager */
printf("this goes straight to the screen\n");
printf("this goes straight to the screen too\n");
printf("and so does this");
The different shells (sh, csh, ksh, etc.) do this type of thing when they
set up pipes. I'm looking for a C function that will do essentially the
same thing (without the shell overhead).
