+ * After the dump is complete it copies the dump to the provided
+ * user space buffer.
+ *
+ * @param ocs Pointer to ocs structure
+ * @param buf User space buffer in which to store the dump
+ * @param buflen Length of the user buffer in bytes
+ *
+ * @return Returns 0 on success, non-zero on error.
