Subject: [PATCH 4/8] Make lib/prio_tree.c a stand-alone library
Date: Tue,  4 Apr 2017 23:22:14 +0300	[thread overview]
Message-ID: <20170404202218.52260-4-tkusumi@tuxera.com> (raw)
In-Reply-To: <20170404202218.52260-1-tkusumi@tuxera.com>

From: Tomohiro Kusumi <tkusumi@tuxera.com>

lib/prio_tree.c not having dependency on fio.h enables it to be
a stand-alone library, which is useful for debugging purpose.
In fact, most of the files under lib/ directory do things this way.

 # cat ./test2.c
 #include <stdio.h>
 #include "lib/prio_tree.h"
 int main(void) {
         struct prio_tree_root tree;
         struct prio_tree_node node;
         INIT_PRIO_TREE_ROOT(&tree);
         INIT_PRIO_TREE_NODE(&node);
         prio_tree_insert(&tree, &node);
         prio_tree_remove(&tree, &node);
         printf("%d\n", prio_tree_empty(&tree));
         return 0;
 }
 # gcc -Wall -g -DBITS_PER_LONG=64 ./test2.c ./lib/prio_tree.c
 # ./a.out
