I have some code that looks like this:
opendir(MYDIR, $dirname);
while (condition) #condition ~ 1, loop basically forever
{
 my @mail = grep { $_ ne '.' and $_ ne '..' } readdir INDIR;
 foreach (@mail)
 {
  # do stuff
  # delete each file
 }
 undef(@mail);
 # @mail shuld be empty now
 sleep(1); # give cpu a break
}
# more stuff...
closedir(MYDIR);

The readdir works fine the first time through the loop. All of the files are processed and deleted once processed. Any files that are added to the directory after the first execution of the loop, however, are never found by the readdir command. Do I need to close the directory and reopen it at each iteration (I hope not)? Are the results of readdir cached somewhere perhaps? I looked at the function reference in the Camel book (3rd ed) and didn't notice any gotchas about using readdir in a loop situation. Any ideas?
