How to delete the temporary files?

[GoogleCodeExporter]

I have a loop in my program and at each iteration I'm creating a plot that
is displayed. But since there are more than GP_MAX_TMP_FILES iterations I
get an exception. How do I properly clean up the temporary files in each
iteration?

What steps will reproduce the problem?
1. Create more than GP_MAX_TMP_FILES plots.

What version of the product are you using? On what operating system?
I'm using the latest version running on linux.

The void Gnuplot::remove_oldest_tmpfile() is very helpful! I made one addition, though, to check if the file exists before attempting to delete it (otherwise I kept getting segmentation faults and kept crashing my program). I altered the function so it looks something like this:

void Gnuplot::remove_oldest_tmpfile(){
if ((tmpfile_list).size() > 0)
{
struct stat buffer;
if (stat (tmpfile_list[0].c_str(), &buffer) == 0) { // check if file exists
remove (Gnuplot::tmpfile_list[0].c_str() );
}
else {
std::cout << "oldest tmp file DNE \n\n";
}
Gnuplot::tmpfile_list.erase(Gnuplot::tmpfile_list.begin());
Gnuplot::tmpfile_num=tmpfile_list.size();
}
}

Thanks for the help!
