apr_memnode_t Struct Reference
[Internal Memory Allocation]

#include <apr_allocator.h>

Data Fields
apr_memnode_t *	next
apr_memnode_t **	ref
apr_uint32_t	index
apr_uint32_t	free_index
char *	first_avail
char *	endp

Detailed Description

basic memory node structure

Note:

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().
