lib:FileCache
See the current Perl documentation for lib:FileCache.
Here is our local, out-dated (pre-5.6) version:
FileCache - keep more files open than the system permits
cacheout $path; print $path @data;
The cacheout
function will make sure that there's a filehandle open for writing
available as the pathname you give it. It automatically closes and re-opens
files if you exceed your system file descriptor maximum.
BUGS
sys/param.h lies with its NOFILE
define on some systems, so you may have to set $FileCache::cacheout_maxopen
yourself.
