/*
 * The following documents macros defined in this file that work to
 * access and manipulate the data in an rwRec.  Although these are
 * macros, they have been documented as functions in order to convey
 * the expected types of the arguments.
 *
 * ****  Convenience macros  ****
 *
 *   void RWREC_CLEAR(rwRec *r);
 *    Zero out the record, and set Sensor ID and Flowtype to invalid
 *    values.
 *
 *   void RWREC_COPY(rwRec *dst, const rwRec *src);
 *    Copy the rwRec from 'src' to 'dst'.
 *
 *   int rwRecIsICMP(const rwRec *r);
 *    Returns non-zero if the record is an ICMP record, zero otherwise.
 *
 *   int rwRecIsWeb(const rwRec *r);
 *    Returns non-zero if the record can be represented using the SiLK
 *    web-specific file formats, zero otherwise.
 *
 *
 * **** More macros ****
 *
 * Function versions of all of the following macros exist.  Simply
 * change the "rwRec" prefix of the macro to "rwrec_" to use the
 * function version.
 *
 * ***  Whether a record is IPv6  ***
 *
 * int      rwRecIsIPv6(const rwRec *r);
 *
 * ***  Set record as IPv4 or IPv6  ***
 *
 * void     rwRecSetIPv6(rwRec *r);
 * void     rwRecSetIPv4(rwRec *r);
 *
 * It is important to note that the above two macros do not do any
 * conversions on the contained IP addresses.  They are primarily to
 * be used when creating a new rwRec from scratch.  See the following
 * for conversion.
 *
 * ***  Convert record to IPv4 or IPv6  ***
 *
 * int      rwRecConvertToIPv4(rwRec *r);
 * void     rwRecConvertToIPv6(rwRec *r);
 *
 * These macros convert an rwRec to IPv4 or IPv6.  The latter always
 * succeeds.  The former will return -1 if unable to convert due to
 * the existence of IPv6 addresses that cannot be represented as IPv4
 * (and return zero on success).
 *
 * ****  rwRec accessor macros ****
 *
 * Most of the following accessor macros come in five standard
 * variations:
 *
 *   <fieldtype> rwRecGet<field>(const reRec *r)
 *    Gets the value of the field directly
 *
 *   void rwRecSet<field>(rwRec *r, <fieldtype> in_v)
 *    Sets the value of the field to 'in_v'
 *
 *   void rwRecMemGet<field>(const rwRec *r, <fieldtype> *out_vp)
 *    Copies the value of the field to location out_vp
 *
 *   void rwRecMemSet<field>(rwRec *r, const <fieldtype> *in_vp)
 *    Copies the value in location in_vp into the field
 *
 *   int rwRecMemCmp<field>(const rwRec *r, const <fieldtype> *vp)
 *    Compares the field to the value in location vp, returning a
 *    negative integer if the field is less than vp, 0 if equal, and a
 *    positive integer if greater than vp.
 *
 * For the rwRecMem{Get,Set,Cmp}<field>() macros, we use of
 * <fieldtype> in the comment to explain the size of the data
 * involved.  With the exception of those dealing the skipaddr_t
 * objects, the actual functions use void pointers; as a result, those
 * macros do not require the value pointer to be aligned.  The macros
 * that handle values larger than uint8_t use memcpy() or memcmp() to
 * copy or compare the values.
 *
 * ** IP Address Macros **
 *
 * For handling IP addresses, there are three sets of macros: one for
 * IPv4 addresses: one for IPv6 addresses, and one for skipaddr_t
 * objects, which can represent either an IPv4 address or and IPv6
 * object.
 *
 * In addition to the Get, Set, and Comparison macros, the follow
 * macro exists in IPv4, IPv6, and skipaddr_t varieties:
 *
 *   void rwRecApplyMask<field>(rwRec *r, const <fieldtype> mask);
 *    Modify the rwRec's <field> IP addresses by applying the
 *    specified mask (using a bit-wise AND) to that IP address.
 *
 * All of the macros that deal with IPv4 addresses assume that you
 * know the rwRec holds IPv4 addresses.  No conversion of the rwRec or
 * of the address occurs.
 *
 * Using the Get macros for IPv6 on an rwRec that contains V4 data
 * will return a properly encoded IPv4-in-IPv6 address.  All other
 * macros for IPv6 assume you know that the rwRec holds IPv6
 * addresses.  For IPv6, the rwRecGet<field>() and rwRecSet<field>()
 * macros do not exist; you must use the rwRecMemGet<field>() and
 * rwRecMemSet<field>() versions.
 *
 * Since an skipaddr_t can hold an IPv4 or an IPv6 address, the macros
 * that use skipaddr_t objects will correctly handle with rwRecs that
 * hold IPv4 or IPv6 data.  Setting or masking an IPv4 rwRec with an
 * IPv6 skipaddr_t may convert the record to IPv6.  The comparison
 * macros will operate in IPv6 space if either argument involves IPv6.
 * Unlike all other rwRecMem{Get,Set,Cmp}<field>() macros, the
 * functions that work with skipaddr_t pointers require the skipaddr_t
 * to be properly aligned.
 *
 * The IPv4 macros include an extra DEPRECATED macro:
 *
 *   uint32_t rwRecGetMask<field>v4(rwRec *r, uint32_t mask)
 *    Gets the value of the field with the given bit-mask applied
 *

 * void     rwRecMemGetTcpState(const rwRec *r, uint8_t *out_vp);
 * void     rwRecMemSetTcpState(rwRec *r, const uint8_t *in_vp);
 * int      rwRecMemCmpTcpState(const rwRec *r, const uint8_t *vp);
 *
 * The TCP state field is a bit field which states certain miscellaneous
 * information about the flow record.  The following constants are
 * defined which represent this information:
 *
 * #define SK_TCPSTATE_EXPANDED              0x01
 *  Expanded TCP-flags: This bit must be set if and only if the flow
 *  is TCP and the init_flags and rest_flags fields are set.
 *
 * #define SK_TCPSTATE_FIN_FOLLOWED_NOT_ACK  0x08
 *  Flow received packets following the FIN packet that were not ACK or
 *  RST packets.
 *
 * #define SK_TCPSTATE_UNIFORM_PACKET_SIZE   0x10
 *  Flow has packets all of the same size
 *
 * #define SK_TCPSTATE_TIMEOUT_KILLED        0x20
 *  Flow ends prematurely due to a timeout by the collector.
 *
 * #define SK_TCPSTATE_TIMEOUT_STARTED       0x40
 *  Flow is a continuation of a previous flow that was killed
 *  prematurely due to a timeout by the collector.
 *
 * Note: the most significant bit of tcp_state (0x80) is used as a flag
 * to mark a record as having IPv6 addresses.  The rwRecSetIPv4() and
 * rwRecSetIPv6() macros should be used to modify this bit.
 *
 * Be careful when setting the TCP state.  You usually want get the
 * current TCP state, add or remove specific bits by masking, then set it
 * with the resulting value.
 *
 * ***  Application  ***
 *
 * uint16_t rwRecGetApplication(const rwRec *r);
 * void     rwRecSetApplication(rwRec *r, uint16_t in_v);
 * void     rwRecMemGetApplication(const rwRec *r, uint16_t *out_vp);
 * void     rwRecMemSetApplication(rwRec *r, const uint16_t *in_vp);
 * int      rwRecMemCmpApplication(const rwRec *r, const uint16_t *vp);
 *
 * The application field can be set by the yaf flow generation
 * software when it is configured with the "applabel" feature.  This
 * feature causes yaf to inspect the packets in the flow and guess as
 * to the type of application (HTTP, SMTP, SSH, etc) the packets
 * represent.  The value for the field is the standard service port
 * for that service (80, 25, 22, etc).
 *
 * ***  Memo  ***
 *
 * uint16_t rwRecGetMemo(const rwRec *r);
 * void     rwRecSetMemo(rwRec *r, uint16_t in_v);
 * void     rwRecMemGetMemo(const rwRec *r, uint16_t *out_vp);
 * void     rwRecMemSetMemo(rwRec *r, const uint16_t *in_vp);
 * int      rwRecMemCmpMemo(const rwRec *r, const uint16_t *vp);
 *
 * Currently unused.
 *
 * ***  ICMP Type and Code is derived from the DPort  ***
 *
 * uint8_t  rwRecGetIcmpType(const rwRec *r);
 * void     rwRecSetIcmpType(rwRec *r, uint8_t in_v);
 * void     rwRecMemGetIcmpType(const rwRec *r, uint8_t *out_vp);
 *
 * uint8_t  rwRecGetIcmpCode(const rwRec *r);
 * void     rwRecSetIcmpCode(rwRec *r, uint8_t in_v);
 * void     rwRecMemGetIcmpCode(const rwRec *r, uint8_t *out_vp);
 *
 * uint16_t rwRecGetIcmpTypeAndCode(const rwRec *r);

 * int      rwRecMemCmpIcmpTypeAndCode(const rwRec *r, const uint16_t *vp);
 *
 * Since the ICMP Type and Code are stored in the dport field, modifying
 * these will modify the return value of rwRecGetDPort() and friends.
