APR::BucketAlloc - Perl API for Bucket Allocation


  use APR::BucketAlloc ();
  $ba = APR::BucketAlloc->new($pool);


"APR::BucketAlloc" is used for bucket allocation.


Create an "APR::BucketAlloc" object:

  $ba = APR::BucketAlloc->new($pool);
The pool used to create this object.
The new object.

This bucket allocation list (freelist) is used to create new buckets (via "APR::Bucket->new") and bucket brigades (via "APR::Brigade->new").

You only need to use this method if you aren't running under httpd. If you are running under mod_perl, you already have a bucket allocation available via "$c->bucket_alloc" and "$bb->bucket_alloc".


  use APR::BucketAlloc ();
  use APR::Pool ();
  my $ba = APR::BucketAlloc->(APR::Pool->pool);
  my $eos_b = APR::Bucket::eos_create($ba);


Destroy an "APR::BucketAlloc object":

The freelist to destroy.

Once destroyed this object may not be used again.

You need to destroy $ba only if you have created it via "APR::BucketAlloc->new". If you try to destroy an allocation not created by this method, you will get a segmentation fault.

Moreover normally it is not necessary to destroy allocators, since the pool which created them will destroy them during that pool's cleanup phase.
