[Octave-bug-tracker] [bug #46417] GL2PS info: OpenGL feedback buffer overflow when printing

[Pantxo Diribarne]

Follow-up Comment #18, bug #46417 (project octave):

@ederag: I am at 21011:d9f4e4961e09 on default.

@jwe: I was looking for a way to discard previous content of the temporary
file while keeping access to the original file pointer that I had passed to
unwind_protect. You are right that fseek+ftruncate is simpler but I didn't
know of ftruncate hence the use of freopen.
I didn't know about gnulib::tmpfile either and it seams to do exactly what I
want without bothering with fclose/unlink in unwind_protect. Thanks
I attached an updated patch. You need to run "bootstrap" first as I added
gnulib::ftruncate. 
I used the following for tests:


pcolor (rand (200));
## pdf terminal
print -dpdflatexstandalone try.tex
## others based on eps terminal
terms = {".png", ".jpg", ".ps", ".pdf"}
cellfun (@(s) print (["try" s]), terms)



>> The error function no longer returns so you don't need an "else" after
that
After what?
