Data Fields

apr_memnode_t ** ref
apr_uint32_t index
apr_uint32_t free_index
char * first_avail
char * endp

Detailed Description

basic memory node structure

The next, ref and first_avail fields are available for use by the caller of apr_allocator_alloc(), the remaining fields are read-only. The next field has to be used with caution and sensibly set when the memnode is passed back to apr_allocator_free(). See apr_allocator_free() for details. The ref and first_avail fields will be properly restored by apr_allocator_free().
