+ * TALLOC_CTX - indicate that a pointer is used as a talloc parent.
+ *
+ * As talloc is a hierarchial memory allocator, every talloc chunk is a
+ * potential parent to other talloc chunks. So defining a separate type for a
+ * talloc chunk is not strictly necessary. TALLOC_CTX is defined nevertheless,
+ * as it provides an indicator for function arguments.
+ *
+ * Example:
+ * struct foo {
+ * int val;
+ * };
+ *
+ * static struct foo *foo_new(TALLOC_CTX *mem_ctx)
+ * {
+ * struct foo *foo = talloc(mem_ctx, struct foo);
+ * if (foo)
+ * foo->val = 0;
+ * return foo;
+ * }
