Error handling in C is sometimes done by using goto and labels. One of examples in the Linux kernel:
static struct avc_node *avc_alloc_node(void)
{
struct avc_node *node;
node = kmem_cache_zalloc(avc_node_cachep, GFP_ATOMIC);
if (!node)
goto out;
INIT_RCU_HEAD(&node->rhead);
...
A simple trick to avoid "goto" statement
in C and C plus plus, programming, smart code / with 2 comments /
