# FileCache(3pm)

keep more files open than the system permits

## NAME

FileCache - keep more files open than the system permits

## SYNOPSIS

```
    cacheout $path;
    print $path @data;
```

## DESCRIPTION

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.
