-Supported C language subset:
-
-    - Expressions:
-
-        * binary operators, by decreasing priority order: '*' '/' '%',
-          '+' '-', '>>' '<<', '<' '<=' '>' '>=', '==' '!=', '&',
-          '^', '|', '=', '&&', '||'.
-
-        * '&&' and '||' have the same semantics as C : left to right
-          evaluation and early exit.
-
-        * Parenthesis are supported.
-
-        * Comma operator is supported.
-
-        * Trinary operator (?:) is not supported.
-
-        * Unary operators: '&', '*' (pointer indirection), '-'
-          (negation), '+', '!', '~', '++' and '--'.
-
-        * Pointer indirection ('*') is supported.
-
-        * Square brackets are supported.
-
-        * '=' and <op>= are supported.
-
-        * Function calls are supported with standard Linux calling
-          convention. Function pointers are supported.
-          Functions can be used before being declared.
-
-        - sizeof() is not supported.
-
-    - Types:
-        + int, short, char, float, double
-        + pointers
-        + variables can be initialized in declarations.
-        + Only ANSI-style function declarations are supported.
-           - "..." is not supported.
-        - short is supported
-        - const is not supported
-        - signed and unsigned are not supported.
-        - arrays are supported
-        - long doubles are not supported
-        - structs and unions are supported
-        - typedef is supported
-        - explicit storage class specifiers are not supported: register, auto, static, extern
-
-    - Unknown functions and variables are bound at compile time by calling
-      back to the caller. For the 'acc' command-line tool unknown functions
-      and variables are looked up using dlsym, to allow using many libc
-      functions and variables.
-
-    - Instructions: blocks ('{' '}') are supported as in C. 'if' and
-      'else' can be used for tests. The 'while' and 'for' C constructs
-      are supported for loops. 'break' can be used to exit
-      loops. 'return' is used for the return value of a function.
-
-      - switch / case is not supported.
-      - goto and labels are not supported.
-      - continue is not supported.
-
-    - Identifiers are parsed the same way as C. Local variables are
-      handled, but there is no local name space (not a problem if
-      different names are used for local and global variables).
-
-    - Numbers can be entered in decimal, hexadecimal ('0x' or '0X'
-      prefix), or octal ('0' prefix).
-
-    - Float and double constants are supported.
-
-    - '#define' is supported without function like arguments.
-    - Macro recursion is allowed.
-    - Self-referential macros are handled as in gcc.
-    - '#pragma' is supported. The pragma text is passed to a callback function,
-       and is used to implement meta-information.
-    - Other preprocessor directives are ignored.
-
-    - C Strings and C character constants are supported. All ANSI C
-      character escapes are supported.
-
-    - Both C comments ( /* */ ) and C++ comments ( // ... end-of-line ) are
-      supported.
-
-    - Some syntax errors are reported, others may cause a crash.
-
-    - Memory: the code, data, and symbol sizes are limited to 100KB
-      (it can be changed in the source code).

- * General instruction format
- *
- *	insn[cc][mod]	[operands]
- *
- * Those fields with an uppercase format code indicate that the field
- * follows directly after the instruction before the separator i.e.
- * they modify the instruction rather than just being an operand to
- * the instruction. The only exception is the writeback flag which
- * follows a operand.
- *
- *
- * 2 - print Operand 2 of a data processing instruction
- * d - destination register (bits 12-15)
- * n - n register (bits 16-19)
- * s - s register (bits 8-11)
- * o - indirect register rn (bits 16-19) (used by swap)
- * m - m register (bits 0-3)
- * a - address operand of ldr/str instruction
- * e - address operand of ldrh/strh instruction
- * l - register list for ldm/stm instruction
- * f - 1st fp operand (register) (bits 12-14)
- * g - 2nd fp operand (register) (bits 16-18)
- * h - 3rd fp operand (register/immediate) (bits 0-4)
- * b - branch address
- * t - thumb branch address (bits 24, 0-23)
- * k - breakpoint comment (bits 0-3, 8-19)
- * X - block transfer type
- * Y - block transfer type (r13 base)
- * c - comment field bits(0-23)
- * p - saved or current status register
- * F - PSR transfer fields
- * D - destination-is-r15 (P) flag on TST, TEQ, CMP, CMN
- * L - co-processor transfer size
- * S - set status flag
- * P - fp precision
- * Q - fp precision (for ldf/stf)
- * R - fp rounding
- * v - co-processor data transfer registers + addressing mode
- * W - writeback flag
- * x - instruction in hex
- * # - co-processor number
- * y - co-processor data processing registers
- * z - co-processor register transfer registers

+|(struct nlmsghdr)|D|(struct genlmsghdr)|D|

+
+* Each netlink message consists of a bitstream with a netlink header.
+* After this header a second header *can* be used specific to the netlink
+  family in use. This library was tested using the generic netlink
+  protocol defined by struct genlmsghdr to support nl80211.
+* After the header(s) netlink attributes can be appended to the message
+  which hold can hold basic types such as unsigned integers and strings.
+* All data structures in this implementation are byte-aligned (Currently 4 bytes).
+* Acknowledgements (ACKs) are sent as NLMSG_ERROR netlink message types (0x2) and
+  have an error value of 0.
+
+KNOWN BUGS
+* NOT THREAD SAFE!!!
+* nla_parse - does not use nla_policy argument
+* nl_recvmsgs - does not support nl_cb_overwrite_recv()
+* nl_recv - sets/unsets async. flag
+* genl_ctrl_alloc_cache - netlink send/recv funcs should be used

+ * struct nl_object_ops my_ops = {
+ * 	.oo_name	= "my_obj",
+ * 	.oo_size	= sizeof(struct my_obj),
+ * };
+ *
+ * // At this point the object can be allocated, you may want to provide a
+ * // separate _alloc() function to ease allocting objects of this kind.
+ * struct nl_object *obj = nl_object_alloc(&my_ops);
+ *
+ * // And release it again...
+ * nl_object_put(obj);
+ * @endcode
+ *
+ * @par 2) Allocating additional data
+ * @code
+ * // You may require to allocate additional data and store it inside
+ * // object, f.e. assuming there is a field `ptr'.
+ * struct my_obj {
+ * 	NLHDR_COMMON
+ * 	void *		ptr;
+ * };
+ *
+ * // And at some point you may assign allocated data to this field:
+ * my_obj->ptr = calloc(1, ...);
+ *
+ * // In order to not introduce any memory leaks you have to release
+ * // this data again when the last reference is given back.
+ * static void my_obj_free_data(struct nl_object *obj)
+ * {
+ * 	struct my_obj *my_obj = nl_object_priv(obj);
+ *
+ * 	free(my_obj->ptr);
+ * }
+ *
+ * // Also when the object is cloned, you must ensure for your pointer
+ * // stay valid even if one of the clones is freed by either making
+ * // a clone as well or increase the reference count.
+ * static int my_obj_clone(struct nl_object *src, struct nl_object *dst)
+ * {
+ * 	struct my_obj *my_src = nl_object_priv(src);

+ * @par 3) Object Dumping
+ * @code

+ * 				   struct nl_dump_params *params)
+ * {
+ * 	struct my_obj *my_obj = nl_object_priv(obj);

+ * };
+ * @endcode
+ *
+ * @par 4) Object Attributes
+ * @code
+ * // The concept of object attributes is optional but can ease the typical
+ * // case of objects that have optional attributes, e.g. a route may have a
+ * // nexthop assigned but it is not required to.
+ *
+ * // The first step to define your object specific bitmask listing all
+ * // attributes
+ * #define MY_ATTR_FOO		(1<<0)
+ * #define MY_ATTR_BAR		(1<<1)
+ *
+ * // When assigning an optional attribute to the object, make sure
+ * // to mark its availability.
+ * my_obj->foo = 123123;
+ * my_obj->ce_mask |= MY_ATTR_FOO;
+ *
+ * // At any time you may use this mask to check for the availability
+ * // of the attribute, e.g. while dumping
+ * if (my_obj->ce_mask & MY_ATTR_FOO)
+ * 	nl_dump(params, "foo %d ", my_obj->foo);
+ *
+ * // One of the big advantages of this concept is that it allows for
+ * // standardized comparisons which make it trivial for caches to
+ * // identify unique objects by use of unified comparison functions.
+ * // In order for it to work, your object implementation must provide
+ * // a comparison function and define a list of attributes which
+ * // combined together make an object unique.
+ *
+ * static int my_obj_compare(struct nl_object *_a, struct nl_object *_b,
+ * 			     uint32_t attrs, int flags)
