The following adspec definitions apply to the <rapi.h> header:

• Type qos_adspecx_t is defined by typedef as a structure that contains the union of all adspec parameters for controlled-load service and guaranteed service models, and has at least the following members:

  Member	Type	Usage
  General path characterization parameters
  xaspec_flags	u_int8_t	Flags(1)
  xaspec_hopcnt	u_int16_t
  xaspec_path_bw	float32_t
  xaspec_min_latency	u_int32_t
  xaspec_composed_MTU	u_int32_t
  Controlled-load service adspec parameters
  xClaspec_flags	u_int8_t	Flags
  xClaspec_override	u_int8_t	See note (2)
  xClaspec_hopcnt	u_int16_t
  xClaspec_path_bw	float32_t
  xClaspec_min_latency	u_int32_t
  xClaspec_composed_MTU	u_int32_t
  Guaranteed service adspec parameters
  xGaspec_flags	u_int8_t	Flags
  xGaspec_Ctot	u_int32_t
  xGaspec_Dtot	u_int32_t
  xGaspec_Csum	u_int32_t
  xGaspec_Dsum	u_int32_t
  xGaspec_override	u_int8_t	See note (2)
  xGaspec_hopcnt	u_int16_t
  xGaspec_path_bw	float32_t
  xGaspec_min_latency	u_int32_t
  xGaspec_composed_MTU	u_int32_t
  Notes: (1) FLG_IGN is not allowed; FLG_PARM is assumed. (2) A value of 1 means "override all generic parameters."

• The following macros are defined with bitwise-distinct integral values for use in the xaspec_flags xClaspec_flags and xGaspec_flags fields:

  Macro	Meaning
  XASPEC_FLG_BRK	Break bit: service unsupported in some node.
  XASPEC_FLG_IGN	Ignore flag: Do not include this service.
  XASPEC_FLG_PARM	Parms-present flag: Include service parameters.

• Type rapi_adspec_t is defined by typedef as a structure to represent an adspec descriptor, and has at least the following members:

  Member	Type	Usage
  adsbody_u	union
  adsx	qos_adspecx_t	Simplified format adspec
  form	rapi_format_t	adspec format
  ISa	IS_adsbody_t	Int-serv format adspec
  len	unsigned int	Actual length in bytes

• The following macros are defined with the values given below:

  Macro	Value
  adspecbody_IS	adsbody_u.ISa
  adspecbody_qosx	adsbody_u.adsx
