# Math::Prime::Util::MemFree(3pm)

An auto-free object for Math::Prime::Util

## NAME

Math::Prime::Util::MemFree - An auto-free object for Math::Prime::Util

## VERSION

Version 0.73

## SYNOPSIS

```
  use Math::Prime::Util;
  {
    my $mf = Math::Prime::Util::MemFree->new;
    # ... do things with Math::Prime::Util ...
  }
  # When the last object leaves scope, prime_memfree is called.
```

## DESCRIPTION

This is a more robust way of making sure any cached memory is freed, as it will be handled by the last `"MemFree"` object leaving scope.  This means if your routines were inside an eval that died, things will still get cleaned up. If you call another function that uses a MemFree object, the cache will stay in place because you still have an object.

## FUNCTIONS

### new

Creates a new auto-free object.  This object has no methods and has no data. When it leaves scope it will call `"prime_memfree"`, thereby releasing any extra memory that the Math::Prime::Util module may have allocated.

Memory is not freed until the last object goes out of scope.  `"prime_memfree"` may always be called manually.  All memory is freed at `"END"` time, so this is mainly for long running programs that want extra control over memory use.
