Member Data Documentation

const char* apr_bucket_pool::base

The block of data actually allocated from the pool. Segments of this block are referenced by adjusting the start and length of the apr_bucket accordingly. This will be NULL after the pool gets cleaned up.

Definition at line 579 of file apr_buckets.h.

The pool bucket must be able to be easily morphed to a heap bucket if the pool gets cleaned up before all references are destroyed. This apr_bucket_heap structure is populated automatically when the pool gets cleaned up, and subsequent calls to pool_read() will result in the apr_bucket in question being morphed into a regular heap bucket. (To avoid having to do many extra refcount manipulations and b->data manipulations, the apr_bucket_pool struct actually *contains* the apr_bucket_heap struct that it will become as its first element; the two share their apr_bucket_refcount members.)

Definition at line 573 of file apr_buckets.h.

The freelist this structure was allocated from, which is needed in the cleanup phase in order to allocate space on the heap

Definition at line 590 of file apr_buckets.h.

The pool the data was allocated from. When the pool is cleaned up, this gets set to NULL as an indicator to pool_read() that the data is now on the heap and so it should morph the bucket into a regular heap bucket before continuing.
