- * block_pool - An efficient allocator for blocks that don't need to be resized or freed.
- *
- * block_pool allocates blocks by packing them into buffers, making the
- * overhead per block virtually zero. Because of this, you cannot resize or
- * free individual blocks, but you can free the entire block_pool.
- *
- * The rationale behind block_pool is that talloc uses a lot of bytes per
- * block (48 on 32-bit, 80 on 64-bit). Nevertheless, talloc is an excellent
- * tool for C programmers of all ages. Because a block_pool is a talloc
- * context, it can be useful in talloc-based applications where many small
- * blocks need to be allocated.
- *
- * Example:
- *
- * #include <ccan/block_pool/block_pool.h>
- *
- * int main(void) {
- * struct block_pool *bp = block_pool_new(NULL);
- *
- * void *buffer = block_pool_alloc(bp, 4096);
- * char *string = block_pool_strdup(bp, "A string");
- *
- * int array[] = {0,1,1,2,3,5,8,13,21,34};
- * int *array_copy = block_pool_memdup(bp, array, sizeof(array));
- *
- * memset(buffer, 0xff, 4096);
- * printf("string = %s\n", string);
- * printf("array_copy[0] == %i\n", array_copy[0]);
- * block_pool_free(bp);
- * return 0;
- * }
