Memory Pool C Library Source
Download Version 2.1.0 (5/31/2006)
This is a memory pool library managed multiple heaps that can be
allocated and destroyed without fragmenting memory. You can have
multiple heaps and reset them easily completely reclaiming the memory
(as opposed to standard heaps).
With it you can mpool_open() a new heap, then mpool_alloc(),
mpool_calloc(), mpool_realloc(), mpool_free() to your heart's content.
Once you are done with the memory-pool you can run mpool_clear() or
mpool_close() and completely remove the memory associated with the
pools. This is very handy if you are working with some large blocks
of memory and want to reset back to a clean state.
Check out the mpool.h file for more
information. Sorry for minimal docs. If you have any questions or
problems feel free to send me mail.
- mpool_t *mpool_open(const unsigned int flags, const unsigned int
page_size, void *start_addr, int *error_p)
- Open/allocate a new memory pool.
- int mpool_close(mpool_t *mp_p)
- Close/free a memory allocation pool.
- int mpool_clear(mpool_t *mp_p)
- Wipe a memory pool clean so we can start again.
- void *mpool_alloc(mpool_t *mp_p, const unsigned long byte_size,
- Allocate space for bytes inside of an already open memory pool.
- void *mpool_calloc(mpool_t *mp_p, const unsigned long ele_n,
const unsigned long ele_size, int *error_p)
- Allocate space for elements of bytes in the memory pool and zero
the space afterwards.
- int mpool_free(mpool_t *mp_p, void *addr, const unsigned long
- Free an address from a memory pool. This is different
from normal free because it needs the addresses size. Future versions
of the library will not have that restriction.
- void *mpool_resize(mpool_t *mp_p, void *old_addr, const unsigned
long old_byte_size, const unsigned long new_byte_size, int
- Reallocate an address in a memory pool to a new size. This is
different from realloc in that it needs the old address' size. If you
don't have it then you need to allocate new space, copy the data, and
free the old pointer yourself.
- int mpool_stats(const mpool_t *mp_p, unsigned int *page_size_p,
unsigned long *num_alloced_p, unsigned long *user_alloced_p, unsigned
long *max_alloced_p, unsigned long *tot_alloced_p)
- Return stats from the memory pool.
- int mpool_set_log_func(mpool_t *mp_p, mpool_log_func_t log_func)
- Set the Return stats from the memory pool.
- int mpool_set_max_pages(mpool_t *mp_p, const unsigned int max_pages)
- Set the maximum number of pages that the library will use. Once it
hits the limit it will return MPOOL_ERROR_NO_PAGES.
NOTE: if the MPOOL_FLAG_HEAVY_PACKING is set then this max-pages
value will include the page with the mpool header structure in it.
If the flag is _not_ set then the max-pages will not include this
- const char *mpool_strerror(const int error)
- Return the corresponding string for the error number.
